Suggester - how to return exact match?
Hi, we implemented a Solr suggester (http://wiki.apache.org/solr/Suggester) that uses a file based dictionary. We use the results of the suggester to populate a dropdown field of a search field on a webpage. Our dictionary (autosuggest.txt) contains: foo bar Our suggester has the following behavior: We can make a request with the search query "fo" and get a response with the suggestion "foo". This is great. However, if we make a request with the query "foo" (an exact match) we get no suggestions. We would expect that the response returns the suggestion "foo". How can we configure the suggester to return also the perfect match as a suggestion? This is the config for our search component: spellCheck default org.apache.solr.spelling.suggest.Suggester autosuggest.txt Thanks for help! Mirko
Re: Suggester - how to return exact match?
Hi, I'd like to clarify our use case a bit more. We want to return the exact search query as a suggestion only if it is present in the index. So in my example we would expect to get the suggestion "foo" for the query "foo" but no suggestion "abc" for the query "abc" (because "abc" is not in the dictionary). For me this use case seems quite common. Say, we have three products in our store: "foo", "foo 1", "foo 2". If the user types "foo" in the product search, we want to suggest all our products in the dropdown. Is this something we can do with the Solr suggester?

Parse eDisMax queries for keywords
Hi, We would like to implement special handling for queries that contain certain keywords. Our particular use case: In the example query "Footitle season 1" we want to discover the keywords "season" , get the subsequent number, and boost (or filter for) documents that match "1" on field name="season". We have two fields in our schema: Our idea was to use a Keyword tokenizer and a Regex on the "season" field to extract the season number from the complete query. However, we use a ExtendedDisMax query parser in our search handler: edismax title season The problem is that the eDisMax tokenizes the query, so that our field "season" receives the tokens ["Foo", "season", "1"] without any order, instead of the complete query. How can we pass the complete query (untokenized) to the season field? We don't understand which tokenizer is used here and why our "season" field received tokens instead of the complete query. Or is there another approach to solve this use case with Solr? Thanks, Mirko
Re: Parse eDisMax queries for keywords
Hi Jack, thanks for your reply. Ok in this case I agree that "enriching" the query in the application layer is a good idea. We are still a bit puzzled how the enriched query should look like. I'll post here when we found a solution. If somebody has suggestions, I'd be happy to hear them.

Thanks! We solved this issue in the front-end now. I.e. we add the exact match to the list of suggestions there.

Automatically build spellcheck dictionary on replicas
Hi all, We use a Solr SpellcheckComponent with a file-based dictionary. We run a master and some replica slave servers. To update the dictionary, we copy the dictionary txt file to the master, from where it is automatically replicated to all slaves. However, it seems we need to run the "spellcheck.build" query on all servers individually. Is there a way to automatically build the spellcheck dictionary on all servers without calling "spellcheck.build" on all slaves individually? We use Solr 4.0.0 Thanks, Mirko
Re: Automatically build spellcheck dictionary on replicas
Yes, I have that, but it doesn't help. It seems Solr still needs the query with the "spellcheck.build" parameter to build the spellchecker index. 2013/12/3 Kydryavtsev Andrey > Did you try to add > true > parameter to your slave's spellcheck configuration? > > 03.12.2013, 12:04, "Mirko" : > > Hi all, > > We use a Solr SpellcheckComponent with a file-based dictionary.

Solr Suggester ranked by boost
I want to implement a Solr Suggester (http://wiki.apache.org/solr/Suggester)
that ranks suggestions by document boost factor.
As I understand the documentation, the following config should work:
Solrconfig.xml:
...
true
7
true
suggest
default
suggesttext
org.apache.solr.spelling.suggest.Suggester
org.apache.solr.spelling.suggest.fst.WFSTLookupFactory
true
...
Schema.xml:
...
...
...
I added three documents with a document boost:
{
"add": {
"commitWithin": 5000,
"overwrite": true,
"boost": 3.0,
"doc": {
"id": "1",
"suggesttext": "text bb"
}
},
"add": {
"commitWithin": 5000,
"overwrite": true,
"boost": 2.0,
"doc": {
"id": "2",
"suggesttext": "text cc"
}
},
"add": {
"commitWithin": 5000,
"overwrite": true,
"boost": 1.0,
"doc": {
"id": "3",
"suggesttext": "text aa"
}
}
}
A query the suggest handler (with spellcheck.q=te) gives the following
response:
{
"responseHeader":{
"status":0,
"QTime":6},
"command":"build",
"response":{"numFound":3,"start":0,"docs":[
{
"id":"1",
"suggesttext":["text bb"]},
{
"id":"2",
"suggesttext":["text cc"]},
{
"id":"3",
"suggesttext":["text aa"]}]
},
"spellcheck":{
"suggestions":[
"te",{
"numFound":3,
"startOffset":0,
"endOffset":2,
"suggestion":["text aa",
"text bb",
"text cc"]}]}}
The search results are ranked by boost as expected. However, the
suggestions are not ranked by boost (but alphabetically instead). I also
tried the TSTLookup and FSTLookup lookup implementations with the same
result.
Any ideas what I'm missing?
Thanks,
Mirko

Indexing XML files
Hi, I am trying to index an xml file as a field in lucene, see example below: As You Like it Shakespeare, William here goes the xml... I can index the title and author fields because they are strings, but the record field is an xml itself and I bump into some problems as I cannot directly input an xml file using the post.sh script (solr complains). I wonder what would be the correct (and relatively simple) way of doing it. Ideally, I would like to store the xml as is, and index only the content removing the xml-tags (I believe there is HTMLStripWhitespaceAnalyzer for that). And output the result as an xml (so, simple escaping does not work for me). So far, I had the idea of escaping the xml record and then unescaping it for inner storage and using the analyzer for indexing (which would possible require creating a class like XMLField or such). thanks, mirko
Re: Indexing XML files
Hi, Thanks for the quick response. Now, I have one more question. Is it possible to get the result for a query back in the following form (considering the input is the escaped xml, what you mentioned before): 0 0 As You Like It (Promptbook of McVicars 1860)Shakespeare, William, ... Note, that the here the xml data is not escaped. If yes, what do I have to do to get such results back? Would need to be replaced with a type, say, which has a different write method? Or will I only be able to display escaped xml within (and any other types). If so, why? thanks, mirko Quoting Chris Hostetter <[EMAIL PROTECTED]>: > > Since XML is the transport for sending data to Solr, you need to make sure > all field values are XML escaped. > > If you wanted to index a plain text "title" and that tile contained an > ampersand character > > Sense & Sensability > > ...you would need to XML escape that as... > > Sense & Sensability > > ...Solr internally will treat that consistently as the JAva string "Sense > & Sensability" and when it comes time to return that string back to your > query clients, will output it in whatever form is appropraite for your > ResponseWriter -- if that's XML, then it will be XML escaped again, if > it's JSON or something ike it, it can probably be left alone. > > The same holds tru for any other characters you wna to include in your > field values: Solr doens't care that they *value* itself is an XML string, > just that you properly escape the value in your XML message to > Solr... > > > >As You Like it >Shakespeare, William ><myxml>here goes the > xml...</myxml> > > > > ...does that make sense? > > : Ideally, I would like to store the xml as is, and index only the content > : removing the xml-tags (I believe there is HTMLStripWhitespaceAnalyzer for > : that). > : And output the result as an xml (so, simple escaping does not work for me). > > the escaping is just to send the data to Solr -- once sent, Solr will > process the unescaped string when deailing with analyzers, etc exactly as > you'd expect. > > > -Hoss >

You are right, it is escaped.

Re: Indexing XML files
Hi, the idea is to apply XSLT transformation on the result.

Re: Indexing XML files
Thank you all for the quick responses. They were very helpful.
My XML is well-formed, so I ended up implementing my own FieldType:
public class XMLField extends TextField {
public void write(XMLWriter xmlWriter, String name, Fieldable f) throws
IOException {
xmlWriter.writePrim("xml", name, f.stringValue(), false);
}
}
I looked at the XSD and there is one thing I don't understand:
If the desired way is to conform to the XSD (and hence the types used in XSD),
then how would it possible to use user-defined fieldtypes as plugins? Wouldn't
they violate the same principle?
thanks,
mirko

solr + cocoon problem
Hi,
I am trying to implement a cocoon based application using solr for searching.
In particular, I would like to forward the request from my response page to
solr. I have tried several alternatives, but none of them worked for me.
One which would seem a logical way to me is to have response page, which is
forwarded to solr with cocoon's file generator. It works fine if I perform
queries which contain only alphanumeric characters, but it gives the following
error if I try to query for a string containing nonalphanum characters:
http://hostname/cocoon/mywebapp/response?q=a+b
java.io.IOException: Server returned HTTP response code: 505 for URL:
http://hostname/solr/select/?q=a b
The interesting thing is that if I access http://hostname/solr/select/?q=a b
directly it works.
The relevant part of my sitemap.xmap:
http://hostname/solr/select/?q={request-param:q}";
type="file" >
Any ideas on how to implement a cocoon layer above solr?
thanks,
mirko
ps. I realize this question might be more of a cocoon question, but I am
posting it here because I have gotten the idea from
http://wiki.apache.org/solr/XsltResponseWriter to use cocoon on top of solr)
So, I assume some of you have already had run into similar issues and/or knows
the solution...
Re: solr + cocoon problem
Hi, I agree, this is not a legal URL. But the thing is that cocoon itself is sending the unescaped URL.

SolrSearchGenerator for Cocoon (2.1)
Hi, I looked at the SolrSearchGenerator (this is the part which is of interest to me), but I could not get it work for Cocoon 2.1 yet. It seems that the there is no getParameters method for the org.apache.cocoon.environment interface: http://cocoon.apache.org/2.1/apidocs/org/apache/cocoon/environment/Request.html I guess you using the getParameterNames and getParameter methods instead should do the trick.

Re: Filter query doesn't always work...
Hi, you might want to use the sint (sortable integer) fieldtype instead. If you use the integer fieldtype I guess the range queries are treated as string prefixes (like in [Ab TO Ch]).

numFound for facet results
Hi, could you tell me what is the (simplest|elegant|fast) way of implementing the following: I use faceted browsing, but I limit the number of facet counts to 5 (i.e., facet.limit=5). 1. I would like to be able to show if there are more facet values (this can be achieved with the trick for asking 6 values and only displaying 5 and if the 6th is non-empty obviously there are more than 5 :) 2. I would like to be able to tell how many facet values are there total. (This would be a value like numFound for the results). Is there such a thing or a workaround like for 1. thanks, mirko
problem with schema.xml
Hi, I just started playing around with Solr 1.2. It has some nice improvements. I noticed that errors in the schema.xml get reported in a verbose way now, but the following steps cause a problem for me: 1. start with a correct schema.xml - Solr works fine 2. edit it in a way that is no longer correct (say, remove the closing tag - Solr works fine 3. restart the webapp (through the Tomcat manager interface) - Solr complains that the schema.xml does not parse, fine. 4. now restart again (without fixing the schema.xml!) - Solr won't even start up 5. fix the above problem (add the closing tag) and restart via Tomcat's manager - the webapp cannot restart showing that there is a problem: FAIL - Application at context path /furness could not be started The following steps might seem artificial, but assume you don't manage to fix all the typos in your schema.xml for the first attempt. It seems after restart Solr gets stuck in some state and I cannot get it up and running by Tomcat's manager, only by restarting Tomcat. Am I missing something? Thanks, mirko

Create field date using name file
Hi folks, Hopefully this is an easy question but I couldn't do it after several hours.. I created a new field (adding indexed="true" stored="true"/>) and I'd like to use name file value to fill out it. The name files are like: TEXT_CRE_MMGG_X-XXX-XXX.txt or TEXT_CRE_MMGG_X-XXX.txt (where every X are random numbers). I'd like to use a date field type to be able to use some group functions. Thank in advance. Have a nice week, Mirko

Invalid Date String:'1992-07-10T17'
Hi all,
I am very new with Solr (and Lucene) and I use the last version of it.
I do not understand why I obtain this:
Exception in thread "main"

String a = "speechDate:1992-07-10T17:33:18Z";
query.set("fq", a);
//query.setQuery( a ); <-- I also tried using this one.
According to
https://cwiki.apache.org/confluence/display/solr/Working+with+Dates, it
should be right. I tried with others date, or just |-MM-DD, with no
success.
My goal is to group these speeches (hopefully using date math syntax). I
would like to know if you suggest me to use date or tdate or other
because I have not understood the difference.
Thanks in advance,|

Unless you are truely seraching for only documents that have an *exact*
date value matching your input (down to the millisecond) then seraching or
a single date value is almost certainly not what you want -- you most
likely want to do a range search...
String a = "speechDate:[1992-07-10T00:00:00Z TO 1992-07-11T00:00:00Z]";
(which doesn't require special escaping, because the query parser is smart
enough to know that ":" aren't special inside of the "[..]")
: like to know if you suggest me to use date or tdate or other because I have

the difference between date and tdate has to do with how you wnat to trade
index size (on disk & in ram) with search speed for range queries like
these -- tdate takes up a little more room in the index, but came make
range queries faster.

how to store _text field
Hi folks, I googled and tried without success so I ask you: how can I modify the setting of a field to store it ? It is interesting to note that I did not add _text field so I guess it is a default one. Maybe it is normal that it is not showed on the result but actually this is my real problem. It could be grand also to copy it in a new field but I do not know how to do it with the last Solr (5) and the new kind of schema.

Hi Alexandre, I need to visualize the content of _txt. For some reasons, actual it is not showed in the results (the "response"). I guess that it doesn't happen because it isn't stored (for some default setting that I'd like to change). Thanks for your help, Mirko On 13/03/15 00:27, Alexandre Rafalovitch wrote: Wait, step back.

Re: how to store _text field
Hi Erick, I'm sorry for this delay but I've just seen this reply. I'm using the last version of solr and the default setting is to use the new kind of indexing, it doesn't use schema.xml and for that I have no idea about how set "store" for this field. The content is grabbed because I've obtained results using the search function but it is not showed because it is not setted to "store". I hope to be clear. Thanks very much. All the best, Mirko On 14/03/15 17:58, Erick Erickson wrote: Right, your schema.xml file will define, perhaps, some "dynamic fields". First insure that stored="true" is specified. If you change this, you have to re-index the docs. Second, insure that your "fl" parameter with the field is specified on the requests, something like q=*:*&fl=eoe_txt. Third, insure that you are actually sending content to that field when you index docs. If none of this helps, show us the definition from schema.xml and a sample input document and a query that illustrate the problem please.

Addtion to solr wiki editor list
Hi there! I'd like to be added to the list of people who are able to edit the solr wiki at https://wiki.apache.org/solr. I'm working as a Java developer for a german company using Solr (and like it a lot) a lot and I would like to be able to correct things as soon as I find them without going to the IRC-channel to get things changed. My wiki name should be campfire. Thanks in advance
Re: how to store _text field
Hi guys,
I used the Erick's suggestions (thanks again!!) to create a new field and
copy in it the _text content.
curl -X POST -H 'Content-type:application/json' --data-binary '{
"add-field" : { "name":"content", "type":"string", "indexed":true,
"stored":true}, "add-copy-field" : { "source":"_text", "dest": [
"content"]}}' http://localhost:8983/solr/Test/schema
That seems a good way but I discovered the presence of "bias" in every
content field. Indeed, they start with a string of this kind:
\n \n stream_content_type text/plain \n stream_size 1556 \n
Content-Encoding UTF-8 \n X-Parsed-By
org.apache.tika.parser.DefaultParser \n X-Parsed-By
org.apache.tika.parser.txt.TXTParser \n Content-Type text/plain;
charset=UTF-8 \n resourceName /home/mirko/Desktop/data
sample/sample1/TEXT_CRE_20110608_3-114-500.txt
Now I need to cut off this part but I have no idea also because the path
(present in the last part) has a dynamic length.
For someone could be a problem to have two field with the same content
(double space needed). I have not this problem because I use Solrj to
import, modify and export each document. Maybe I could use it to do also
this but hopefully you know a cleaner method.
Cheers,
Mirko

Near-Realtime-Search, CommitWithin and AtomicUpdates
Hi@all, I'm using Solr 6.6 and trying to validate my setup for AtomicUpdates and Near-Realtime-Search. Some questions are bogging my mind, so maybe someone can give me a hint to make things clearer. I am posting regular updates to a collection using the UpdateHandler and Solr Command Syntax, including updates and deletes. These changes are commited using the commitWithin configuration every 30 seconds. Now I want to use AtomicUpdates on MultiValue'd fields, so I post the "add" commands for these fields only. Sometimes I have to post multiple Solr commands affecting the same document, but within the same commitWithin interval. The question is now, what is the final new value of the field after the atomic update add operations? From my point of view the final value should be the old value plus the newly added values, which is commited to the index in the next commitWithin period. So can I combine multiple AtomicUpdate commands affecting the same document within the same commitWithin interval? Another thing that is bogging me: can I combine multiple AtomicUpdates for the same document with CopyFields? Does Solr use some kind of dirty-read or pending uncommited changes to get the right value of the source field, or is the source always the last commited value? So in summary, does Solr AtomicUpdates use some kind of dirty-read mechanism do do its "magic" ? Thanks in advance, Mirko
