Re: sort by function
Where is your query? You don't search for anything. The q-param is empty. You got two options (untested): remove the q-param or search for something special. I think removing is not a good idea. Instead search for *:* would retrive ALL results that match your filter-query.

Indexing stalls reads
Hey, I'm using solr 1.4 & I've a master / slave setup, I use the slave for all my read operations & commits are scheduled every 20 mins or every 1 docs. Now I think slave shouldn't build index but fetch ones created on Master, but I see it creating indexes, during which all read stalls. Now I don't think thats a common behavior or is there any other way to stop this ? Also how do i stop slave from removing the old indexes till AutoWarming is done ? is there a way to achieve this ? Thnx n Regards, - Manish _ The amazing world in sharp snaps http://news.in.msn.com/gallery/archive.aspx
sort by field length
Hi folks, is it possible to sort by field length without having to (redundantly) save the length information in a seperate index field? At first, I thought to accomplish this using a function query, but I couldn't find an appropriate one. Thanks in advance, Sascha
Dynamically augment search with data
So my need is this: I have a site in which a user does a query for other users. The user can filter the query by different parameters that will limit the result set. One of the things about the system is that the user's can like different objects (Products, Services, etc.). When the user searches the index by a query and it returns a list of users I want to be able to calculate the "shared likes" between the user and each user result in the the returned result set. I would like to then append the calculation in each result in the result set and then sort by the greatest number of "shared likes", thereby making the results more relevant to the user. I would like to have this calculation run before the paging process kicks in so this function will be applied to the result set right before paging. I am using Solr 1.4 and have read just a little on FunctionQuery. Is this what I am needing to perform this task? *~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~ Travis Chase ~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*

Re: Embedded Server, Caching, Stats page updates
So you're right i did miss removing the app deployment but removing that still didn't really do that great. The avg request response time is still slower. The bell curve is a lot more streched than it was before but it doesn't seem to give an overall better performance.

Highlighting a field with a certain value
Hello, How am I able to highlight a field that contains a specific value? If I have a field called type, how am I able to highlight the rows whose values contain something like "title"?
Problem with extended dismax, minus prefix (to mean NOT) and interaction with mm?
I'm running edismax (on both a 1.4 with patch and a branch_3x version) and I'm seeing something I don't expect. We have our mm set such that 2/2 must match and 2/3 must match (mm=2<-1 5<67% A query of dog cat ...gets interpreted as dog AND cat But a query of dog cat -mouse ...gets interpreted as (dog AND cat) OR (dog AND NOT mouse) OR (cat AND NOT mouse) In other words, the "-mouse" is being interpreted as a single token (NOT mouse) to be counted for mm. I would expect the query to interpret as: (dog AND cat) AND (NOT mouse) Are my expectations out of whack? Or is this unexpected behavior? [I've pasted the debugQuery info for a similar search below, though I freely admit to not knowing how to read it] Any thoughts on what I'm seeing here? -Bill- dog cat -trilogy dog cat -trilogy allfields:dog allfields:cat -allfields:trilogi allfields:dog allfields:cat -allfields:trilogi 2.1741915 = (MATCH) sum of: 1.2620605 = (MATCH) weight(allfields:dog in 3187), product of: 0.7618881 = queryWeight(allfields:dog), product of: 8.744003 = idf(docFreq=64, maxDocs=15) 0.08713264 = queryNorm 1.6564907 = (MATCH) fieldWeight(allfields:dog in 3187), product of: 1.7320508 = tf(termFreq(allfields:dog)=3) 8.744003 = idf(docFreq=64, maxDocs=15) 0.109375 = fieldNorm(field=allfields, doc=3187) 0.912131 = (MATCH) weight(allfields:cat in 3187), product of: 0.64770865 = queryWeight(allfields:cat), product of: 7.4335938 = idf(docFreq=240, maxDocs=15) 0.08713264 = queryNorm 1.4082427 = (MATCH) fieldWeight(allfields:cat in 3187), product of: 1.7320508 = tf(termFreq(allfields:cat)=3) 7.4335938 = idf(docFreq=240, maxDocs=15) 0.109375 = fieldNorm(field=allfields, doc=3187) 2.1518915 = (MATCH) sum of: 1.249116 = (MATCH) weight(allfields:dog in 36426), product of: 0.7618881 = queryWeight(allfields:dog), product of: 8.744003 = idf(docFreq=64, maxDocs=15) 0.08713264 = queryNorm 1.6395006 = (MATCH) fieldWeight(allfields:dog in 36426), product of: 2.0 = tf(termFreq(allfields:dog)=4) 8.744003 = idf(docFreq=64, maxDocs=15) 0.09375 = fieldNorm(field=allfields, doc=36426) 0.9027756 = (MATCH) weight(allfields:cat in 36426), product of: 0.64770865 = queryWeight(allfields:cat), product of: 7.4335938 = idf(docFreq=240, maxDocs=15) 0.08713264 = queryNorm 1.3937988 = (MATCH) fieldWeight(allfields:cat in 36426), product of: 2.0 = tf(termFreq(allfields:cat)=4) 7.4335938 = idf(docFreq=240, maxDocs=15) 0.09375 = fieldNorm(field=allfields, doc=36426) 1.4345944 = (MATCH) sum of: 0.832744 = (MATCH) weight(allfields:dog in 37852), product of: 0.7618881 = queryWeight(allfields:dog), product of: 8.744003 = idf(docFreq=64, maxDocs=15) 0.08713264 = queryNorm 1.0930004 = (MATCH) fieldWeight(allfields:dog in 37852), product of: 1.0 = tf(termFreq(allfields:dog)=1) 8.744003 = idf(docFreq=64, maxDocs=15) 0.125 = fieldNorm(field=allfields, doc=37852) 0.6018504 = (MATCH) weight(allfields:cat in 37852), product of: 0.64770865 = queryWeight(allfields:cat), product of: 7.4335938 = idf(docFreq=240, maxDocs=15) 0.08713264 = queryNorm 0.9291992 = (MATCH) fieldWeight(allfields:cat in 37852), product of: 1.0 = tf(termFreq(allfields:cat)=1) 7.4335938 = idf(docFreq=240, maxDocs=15) 0.125 = fieldNorm(field=allfields, doc=37852) 1.2629167 = (MATCH) sum of: 0.624558 = (MATCH) weight(allfields:dog in 30673), product of: 0.7618881 = queryWeight(allfields:dog), product of: 8.744003 = idf(docFreq=64, maxDocs=15) 0.08713264 = queryNorm 0.8197503 = (MATCH) fieldWeight(allfields:dog in 30673), product of: 1.0 = tf(termFreq(allfields:dog)=1) 8.744003 = idf(docFreq=64, maxDocs=15) 0.09375 = fieldNorm(field=allfields, doc=30673) 0.6383587 = (MATCH) weight(allfields:cat in 30673), product of: 0.64770865 = queryWeight(allfields:cat), product of: 7.4335938 = idf(docFreq=240, maxDocs=15) 0.08713264 = queryNorm 0.9855646 = (MATCH) fieldWeight(allfields:cat in 30673), product of: 1.4142135 = tf(termFreq(allfields:cat)=2) 7.4335938 = idf(docFreq=240, maxDocs=15) 0.09375 = fieldNorm(field=allfields, doc=30673) 1.25527 = (MATCH) sum of: 0.728651 = (MATCH) weight(allfields:dog in 29736), product of: 0.7618881 = queryWeight(allfields:dog), product of: 8.744003 = idf(docFreq=64, maxDocs=15) 0.08713264 = queryNorm 0.95637536 = (MATCH) fieldWeight(allfields:dog in 29736), product of: 1.0 = tf(termFreq(allfields:dog)=1) 8.744003 = idf(docFreq=64, maxDocs=15) 0.109375 = fieldNorm(field=allfields, doc=29736) 0.5266191 = (MATCH) weight(allfields:cat in 29736), product of: 0.64770865 = queryWeight(allfields:cat), product of: 7.4335
Re: IndexSearcher and Caches
<>
I have an application deployed on an application server (Weblogic). This
application uses solr to query an index. Users (sessions) will log in to the
application, query and then log out. This login and logout has nothing to do
with solr but the application manages them separately. I am using
EmbeddedSolrServer here.
I think I know where my mistake is. From what you say, it looks to me as
though that I should not create a new SolrIndexSearcher object because Solr
will do this automatically. In my current implementation, I am explicitly
creating a new SolrIndexSearcher object for every new user who logs into the
application.
Let me provide a code snippet to explain further. This is how I initialize
the solr handles required for searching. I am using EmbeddedSolrServer.
SolrConfig solrConfig = new SolrConfig(configHome+"/solrconfig.xml");
IndexSchema indexSchema = new IndexSchema(solrConfig,
configHome+"/schema.xml", null);
File corefile = new File(coreHome, "solr.xml");
CoreContainer coreContainer = new CoreContainer(coreHome, corefile);
CoreDescriptor coreDescriptor = new CoreDescriptor(coreContainer, coreName,
solrConfig.getResourceLoader().getInstanceDir());
coreDescriptor.setConfigName(solrConfig.getResourceName());
coreDescriptor.setSchemaName(indexSchema.getResourceName());
SolrCore solrCore = new SolrCore(coreName, indexHome, solrConfig,
indexSchema, coreDescriptor);
coreContainer.register(coreName, solrCore, false);
SolrServer solrServer = new EmbeddedSolrServer( coreContainer, coreName );
//Next two lines executed for every user
SolrIndexSearcher solrSearcher = solrCore.newSearcher("s1");
SolrRequestParsers solrRequestParsers = new SolrRequestParsers(solrConfig);
Many thanks for the response(s).
Regards

Highlighting is not happening
Hi I am using dismax request handler, I wanted to highlight the search field, So added true I was expecting like if I search for keyword "Akon" resultant docs wherever the Akon is available is bold. But I am not seeing them getting bold, could some one tell me the real path where I should tune If I pass explicitly the hl=true does not work I have added the request handler dismax explicit 0.01 name^20.0 coming^5 playing^4 keywords^0.1 rord(isclassic)^0.5 ord(listeners)^0.3 name, coming, playing, keywords, score 2<-1 5<-2 6<90% 100 *:* true 0 regex regards prakash
Re: Highlighting is not happening
Check that the field you are highlighting on is "stored". It won't work otherwise. Now, this also means that the field is returned from the query. For large text fields to be highlighted only, this means the entire text is returned for each result. There is a pending feature to address this, that allows you to tell Solr to NOT return a specific field (to avoid unecessary transfer of large text fields in this scenario).

Dynamic analyzers
Hi, I have a requirement to dynamically choose a fieldType to analyze text in multiple languages. I will know the language (in a separate field) at index and query time. I've tried implementing this with a custom UpdateRequestProcessorFactory and custom DocumentBuilder.toDocument to change the FieldType, but this dosen't work. I realize I can have e.g. text_en, text_de,... and dynamically populate this with a custom UpdateRequestProcessorFactory, but we are worried with all the languages (lets say 50+) that effectively doing an OR with 50 fields will be a performance issue, is this true? Many thanks in advance, Dan

Re: Highlighting is not happening
Hi Prakash, more importantly, check the field type and its associated analyzer. In case you use a "non-tokenized" type (e.g., string), highlighting will not appear if only a partial field match exists (only exact matches, i.e. the query coincides with the field value, will be highlighted).

Hi Prakash, can you provide 1. the definition of the relevant field 2. your query 3. the definition of the relevant request handler 4. a field value that is stored in your index and should be highlighted -Sascha Doddamani, Prakash wrote: Thanks Sascha, The "type" for fields for which I am searching are all "text" , and I am using solr.TextField Regards Prakash -Original Message- From: Sascha Szott [mailto:sz...@zib.de] Sent: Monday, May 24, 2010 10:29 PM To: solr-user@lucene.apache.org Subject: Re: Highlighting is not happening Hi Prakash, more importantly, check the field type and its associated analyzer.

Re: IndexSearcher and Caches
Ahh, now I understand. No, you need no second IndexSearcher as long as the Server is alive. You can reuse your searcher for every user. The only commands you are executing per user are those to create a search-query.

getting documents sorted after a faceted search
I apply a faceted search and get document ids from the facet_field I have used. Then I search for these documents given ids. id:(id1 id2 ...) But the order is not predictable. (It applies OR) I do not want to sort documents again. Is there any way to get documents in the given id order? -- Furkan Kuru
Re: IndexSearcher and Caches
Thank you I found the API to get the existing SolrIndexSearcher to be present in SolrCore: SolrCore.getSearcher().get() So if now the Index changes (a commit is done) in between, will I automatically get the new SolrIndexSearcher from this call ?

Re: IndexSearcher and Caches
Good question. Well, I never worked productively with SolrJ. But two things: The first: As the documentation says, you *should* get your IndexSearcher from your SolrQueryRequest-object. The second: As a developer of the SolrJ I would do as much as I can automatically behind the curtain. That means that if you do a commit, the index searcher should be automatically renewed. But that's a guess. I can't answer you this question, sorry. Maybe this link helps? http://lucene.472066.n3.nabble.com/Solr-commit-issue-td770315.html#a770453 (searched with the following keywords: solrj commit searcher) I am new to Java and the concept of Java Enterprise Edition's Servlets is not yet fully clear to me. Please, let me ask a question. Let me give you an example: If I use inside my application (it's a Servlet) a SolrServer, I should create him when I start the Servlet. Should I cache the instantiated SolrServer-object with the help of the servlet's cache? And should my cache-implementation should provide a getSolrServer()-method? Maybe this is a question more related to the JavaEE-concept. Thank you.

Faceted search not working?
I'm trying to perform a faceted search without any luck. Result set doesn't return any facet information... http://localhost:8080/solr/select/?q=title:*&facet=on&facet.field=title I'm getting the result set, but no face information present? Is there something else that needs to happen to turn faceting on? I'm using latest Solr 1.4 release. Data is indexed from the database using dataimporter. Thanks. Ilya Sterin

Re: Faceted search not working?
it's probably because your query isn't matching anything. try q=title: [* TO *], or maybe even simply *:* if you are trying to match all documents.

Re: Commits, facet autowarming and hung searches

Re: query parser for boost query text
: Special characters in the text used for boost queries are not removed. For : example, bq=field1:(what is xyz?)^10 gets parsed into query field1:xyz?10 : (what and is are stop words). Question mark didn't get removed -- field1 : uses standard tokenizer and standard filter, so I expect it to get removed. : When I test it using the analysis page agains field1, question mark did get : removed. unless you are using some special QParser that you haven't mentioned, i supsect that what you are seeing is that since "?" is a special character for wildcard searchers, you are still seeing it appear in the debugQuery output showing hte toString of your query. in general, if your analyzer removes punctuation, then the punctuation will be removed -- but the exception is when thta punctuation is a "special character" for your quer parser -- then it has special meaning. -Hoss
Re: Issues with clustering in multicore
: so i edit the solrconfig.xml in tht file to add clustering information (i : did make sure that the lib declaration points to the correct location). are you sure? ... did you see log messages (prior to the stack trace below) inidcating that the clustering jar was being loaded? SolrResourceLoader logs an info message for every jar it loads, so if you don't see the clustering jar in that list, that's why it can't find it. (and even if you do see it, it might be getting loaded by a differnet core then the one you are trying to use it in, so initializing Solr with a single core first to sanity check may be a good idea) -Hoss
Re: IndexSearcher and Caches
: Thank you I found the API to get the existing SolrIndexSearcher to be : present in SolrCore: : SolrCore.getSearcher().get() I think perhaps you need to take 5 big steps back and explain what your goal is. 99.999% of all solr users should never care about that method -- even the 99.9% of the folks writing java code and using "EmbeddedSolr" should never ever have a need to call those -- so what exactly is it you are doing, and how did you get along hte path you find yourself on? this thread started with some fairly innoculous questions about how caches worked in regardes to new searchers -- which is all fine and dandy, those concepts that solr users should be aware of ... in the abstract. you should almost never be instantiating those IndexSearchers or Caches yourself.

Re: sort by field length
Are you sure you want to recompute the length when sorting? It's the classic time/space tradeoff, but I'd suggest that when your index is big enough to make taking up some more space a problem, it's far too big to spend the cycles calculating each term length for sorting purposes considering you may be sorting all the terms in your index worst-case. But you could consider payloads for storing the length, although that would still be redundant...

Tagging and excluding Filters
Hi,
I am using the following solution:
http://wiki.apache.org/solr/SimpleFacetParameters#Tagging_and_excluding_Filters
However when I implemented this on I found that I cannot combine different
filter types:
http://search.un-informed.org/search?q=&=&t[23]=malaria&tm=any&s=Search
The above request would generate the following Solr query:
facet=true&fl=*,score&sort=score+desc&start=0&q=(tag_ids:("23"))&facet.field={!ex%3Ddt}organisation_id&facet.field={!ex%3Ddt}tag_ids&facet.field={!ex%3Ddt}addressee_ids&facet.field={!ex%3Ddt}operative_phrase_id&facet.field={!ex%3Ddt}documenttype_id&facet.field={!ex%3Ddt}information_type_id&facet.field={!ex%3Ddt}legal_value&json.nl=map&wt=json&rows=21
Now when I deselect one of the checkboxes I add an fq parameters:
facet=true&fl=*,score&sort=score+desc&start=0&q=(tag_ids:("23"))&facet.field={!ex%3Ddt}organisation_id&facet.field={!ex%3Ddt}tag_ids&facet.field={!ex%3Ddt}addressee_ids&facet.field={!ex%3Ddt}operative_phrase_id&facet.field={!ex%3Ddt}documenttype_id&facet.field={!ex%3Ddt}information_type_id&facet.field={!ex%3Ddt}legal_value&json.nl=map&wt=json&fq={!tag%3Ddt}organisation_id:(-"9")&rows=21
{!tag=dt}organisation_id:(-8)
Now where I am at a loss is when I want to filter in multiple different
sections (like filter both organisations as well as clause information type.
I tried various ways of constructing the fq prameter but I always get a parse
error:
{!tag=dt}(organisation_id:(-8) AND information_type_id:(-1))
{!tag=dt}organisation_id:(-8) AND {!tag=dt}information_type_id:(-1)
For example:
Caused by: org.apache.lucene.queryParser.ParseException: Cannot parse
'organisation_id:(-"9") AND {!tag=dt}information_type_id:(-"1")': Encountered "
"}" "} "" at line 1, column 35.
When running:
facet=true&fl=*,score&sort=score+desc&start=0&q=(tag_ids:("23"))&facet.field={!ex%3Ddt}organisation_id&facet.field={!ex%3Ddt}tag_ids&facet.field={!ex%3Ddt}addressee_ids&facet.field={!ex%3Ddt}operative_phrase_id&facet.field={!ex%3Ddt}documenttype_id&facet.field={!ex%3Ddt}information_type_id&facet.field={!ex%3Ddt}legal_value&json.nl=map&wt=json&fq={!tag%3Ddt}organisation_id:(-"9")+AND+{!tag%3Ddt}information_type_id:(-"1")&rows=21}
Can someone give me a hint?
