Solr query POST and not in GET
Hi, is possible to change Solr sending query method from get to post? because my query has a lot of OR..OR..OR and the log says to me Request URI too large Where can i change it?? thanx -- Gastone Penzo www.solr-italia.it The first italian blog about SOLR
Re: Solr query POST and not in GET
Yes it's possible. Assuming your using SolrJ as a client-library: set: QueryRequest req = new QueryRequest(); req.setMethod(METHOD.POST); Any other client-library should have a similar method. hth, Geert-Jan 2011/3/15 Gastone Penzo > Hi, > is possible to change Solr sending query method from get to post? > because my query has a lot of OR..OR..OR and the log says to me Request URI > too large > Where can i change it?? > thanx > > > > > -- > Gastone Penzo > > www.solr-italia.it > The first italian blog about SOLR >
Re: Solr query POST and not in GET
Please do not cross-post between lists - yours seems like a user query to me, so I'm answering it here. As to your question - Solr does not select the request method - you do. I've just tested it and Solr happily accepts a query via a POST request. However, you'd probably do well to look at other ways to structure your query if you're hitting the URL length limit.

Re: keeping data consistent between Database and Solr
Solandra is great for adding better scalability and NRT to Solr, but it pretty much just stores the index in Cassandra and insulates that from the user. It doesn't solve the problem of allowing quick and direct retrieval of data that need not be searched. I could certainly just use a Solr search query to "directly" access a single document, but that has overhead and would not be as efficient as directly accessing a database. With potentially tens of thousands of simultaneous direct data accesses, I'd rather not put this burden on Solr and would prefer to use it only for searchas it was intended, while simple data retrieval could come from a better equipped database. But my question of consistency applies to all databases and Solr. i would imagine most people maintain separate MySQL and Solr databases.

Solrj performance bottleneck
Hi,
I am using Solrj as a Solr client in my project.
While searching, for a few words, it seems Solrj takes more time to send
response, for eg (8 - 12 sec). While searching most of the other words it
seems Solrj take less amount of time only.
For eg, if I post a search url in browser, it shows the QTime in
milliseconds only.
http://serverName/solr/mydata/select?q=computing&qt=myhandler&fq=category:1
But, if I query the same using Solrj from my project like below, it takes
long time(8 - 12 sec) to produce the same results. Hence, I suspect whether
Solrj takes such long time to produce results.
SolrServer server = new CommonsHttpSolrServer(url);
SolrQuery query = new SolrQuery("computing");
query.setParam("qt", "myhandler");
query.setFilterQueries("category:1");
query.setHighlight(false);
QueryResponse rsp = server.query( query );
I have tried both POTH and GET method. But, both are taking much time.
Any idea why Solrj takes such long time for particular words. It returns
around 40 doc list as a search result. I have even comment out highlighting
for that.
And any way to speed it up.
Note: I am using Tomcat and set heap size as around 1024 mb.
Thanks,

The QTime does not measure the time to stream back the response (which includes loading stored fields). Since the response is streamed, it's not possible to include this time. The difference normally isn't that large unless you have a network issue, a client that is taking a long time to read the response, or a very large index and not enough free RAM for the OS to cache all the files. Check the solr logs and make sure that equivalent queries are being received. The QTime is also logged. -Yonik http://lucidimagination.com

Dismax: field not returned unless in sort clause?
We have a "D" field (string, indexed, stored, not required) that is returned * when we search with the standard request handler * when we search with dismax request handler _and the field is specified in the sort parameter_ but is not returned when using the dismax handler and the field is not specified in the sort param. IOW, if I do the following query (no sort param), I get all the expected results, but the D field never comes back... &q=&q.alt=*:*&defType=dismax&tie=0.1&mm=1&qf=A,B,C&start=0&rows=300&fl=D ...but if I add "D" to the sort param, the D field comes back on every single record &q=&q.alt=*:*&defType=dismax&tie=0.1&mm=1&qf=A,B,C&start=0&rows=300&fl=D&sort=D%20asc &q=&q.alt=*:*&defType=dismax&tie=0.1&mm=1&qf=A,B,C&start=0&rows=300&fl=D&sort=D%20desc If I omit the fl param, I see that all of our other fields appear to be returned on every result without any need to specify them in the sort param. Obviously, I cannot hard-code the sort order around the D field. :) Any ideas?

RE: keeping data consistent between Database and Solr
I use Solr + MySql with data coming from several DHI type "loaders" that I have written to move data from many different databases into my "BI" solution. I don't use DHI because I am not simply replicating the data, but I am moving/merging/processing the incoming data during the loading. For me, I have an Aspect (aspectj) which wraps my Data Access Object and every time a "persist" is called (I am using hibernate), I update Solr with the same data an instant later using @Around advice. This handles nearly every event during the day. I have a simple "retry" procedure on my Solrj add/commit on network error in hopes that it will eventually work. In case of error I rebuild the solr index from scratch each night by recreating it based on the data in MySQL. That takes about 10 minutes and I run it at night. This allows for me to have "eventual consistency" for any issues that cropped up during the day. Obviously the size of my database (< 2 million records) makes this approach manageable. YMMV.

In 3.1 and trunk (4.0-dev), you could sort by a function query that maps values of 0 to something very large. sort=map(price,0,0,99) asc This should map anything with a price between 0 and 0 to 99 for the purposes of sorting. http://wiki.apache.org/solr/FunctionQuery -Yonik http://lucidimagination.com
Faceting help
Hello list, I'm trying to use facet's via widget's within Ajax-Solr. I have tried the wiki for general help on configuring facets and constraints and also attended the recent Lucidworks webinar on faceted search. Can anyone please direct me to some reading on how to formally configure facets for searching. Currently my facets are configured as follows 'facet.field': [ 'topics', 'organisations', 'exchanges', 'countryCodes' ], 'facet.limit': 20, 'facet.mincount': 1, 'f.topics.facet.limit': 50, 'f.countryCodes.facet.limit': -1, 'facet.date': 'date', 'facet.date.start': '1987-02-26T00:00:00.000Z/DAY', 'facet.date.end': '1987-10-20T00:00:00.000Z/DAY+1DAY', 'facet.date.gap': '+1DAY', 'json.nl': 'map' However I wish to change the fields to contain some constraints such as Topics < field Legislation < constraint Guidance/Policies < constraint Customer Service information/complaints procedure < constraint financial information < constraint etc etc Source < field html < constraint < constraint pdf < constraint email < constraint etc etc Date < field < constraint Basically I need resources to understand how to implement the above instead of the example I currently have.

Re: Solr performance issue
The host is dual quad-core, each Xen VM has been given two CPUs. Not counting dom0, two of the hosts have 10/8 CPUs allocated, two of them have 8/8. The dom0 VM is also allocated two CPUs. I'm not really sure how that works out when it comes to Java running on the VM, but if at all possible, it is likely that Xen would try and keep both VM cpus on the same physical CPU and the VM's memory allocation on the same NUMA node. If that's the case, it would meet what you've stated as the recommendation for incremental mode. Shawn On 3/15/2011 9:10 AM, Markus Jelsma wrote: CMS is very good for multicore CPU's.

I'd actually been sorting on multiValued fields for some time without any problems before this, not sure how Solr was able to handle this in the past... In any case, I'd like to be able to sort on multiValued fields via a function query, but keep getting the following error: can not use FieldCache on multivalued field I've tried using the function 'sum', 'max', and 'min' with the same result.

Re: keeping data consistent between Database and Solr
That's pretty interesting to use the autoincrementing document ID as a way to keep track of what has not been indexed in Solr. And you overwrite this document ID even when you modify an existing document. Very cool. I suppose the number can even rotate back to 0, as long as you handle that. I am thinking of using a timestamp to achieve a similar thing. All documents that have been accessed after the last Solr index need to be added to the Solr index. In fact, each name-value pair in Cassandra has a timestamp associated with it, so I'm curious if I could simply use this. I'm curious how you handle the delta-imports. Do you have some routine that periodically checks for updates to your MySQL database via the document ID? Which language do you use for that?

Re: problem using dataimporthandler
Regarding the DIH problem: I'm encountering "content not allowed in prolog" only when I'm deploying solr on tomcat. I'm using the same data-config.xml in the solr example through jetty and it works fine and I can index the data. Please let me know what should be changed while using tomcat.

bf belongs to DisMaxParams.
Instead try this q={!boost b=boost_score}dog
You can use any valid FuctionQuery as a b paramter.
http://lucene.apache.org/solr/api/org/apache/solr/search/BoostQParserPlugin.html
You may want to use parameter referencing also. Where q is harcoded in
solrconfig.xml, something like:
q={!boost b=$bb v=$qq}&qq=dog&bb=%22ord%28sum%28boost_score,1%29%29

partial optimize does not reduce the segment number to maxNumSegments
I have a core with 120+ segment files and I tried partial optimize specify maxNumSegments=10, after the optimize the segment files reduced to 64 files; I did the same optimize again, it reduced to 30 something; this keeps going and eventually it drops to teen number. I was expecting seeing the optimize results in exactly 10 segment files or somewhere near, and why do I have to manually repeat the optimize to reach that number? thanks Renee -- View this message in context: http://lucene.472066.n3.nabble.com/partial-optimize-does-not-reduce-the-segment-number-to-maxNumSegments-tp2682195p2682195.html Sent from the Solr - User mailing list archive at Nabble.com.

Could possibly be your original xml file was in unicode (with a BOM header - FFFE or FEFF) - xml will see it as content if the underlying file system doesn't handle it.

Re: Faceting help
I'm not sure if I get what you are trying to achieve. What do you mean by "constraint"? Are you saying that you effectively want to filter the facets that are returned? e.g. for source field, you want to show html/pdf/email, but not, say xls or doc?

stopFilterFactor and SnowballPorterFilterFactory not work for Spanish
I am using solr 1.4.1. I am trying to index a spanish field using the
following tokenizer/filters:
Using field analysis solr Admin i can tell StopFilterFactory and
SnowballPorterFilterFactory with Spanish not working right:
1. after stopFilter, "la" should be gone, but it is not.
2. after snowballporterFilterFactory(language=Spanish), "cöcktäils" should
become "cöcktäil". But i still see the token "cöcktäils" coming out.
I configured a spanish stopword list for the StopFilterFactory.
Field name: title_name
field value: la Cöcktäils

Re: Dismax: field not returned unless in sort clause?
: We have a "D" field (string, indexed, stored, not required) that is returned : * when we search with the standard request handler : * when we search with dismax request handler _and the field is specified in : the sort parameter_ : : but is not returned when using the dismax handler and the field is not : specified in the sort param. are you using one of the "sortMissing" options on D or it's fieldType? I'm guessing you have sortMissingLast="true" for D, so anytime you sort on it the docs that do have a value appear first. but when you don't sort on it, other factors probably lead docs that don't have a value for the D field to appear first -- solr doesn't include fields in docs that don't have any value for that field. if my guess is correct, adding "fq=D:[* TO *] to any of your queries will cause the total number of results to shrink, but the first page of results for your requests that don't sort on D will look exactly the same. the LUkeRequestHandler will help you see how many docs in your index don't have any values indexed in the "D" field. -Hoss

Re: background merge hit exception
The stack trace indicates there's an issue with optimizing. How are you kicking off optimizing? Is it automatic or manual? 34G for an index with that many documents does seem excessive. Are you re-indexing the same content with the same unique key? In other words do you have a large number of deleted documents in your index? You can tell by looking at your admin page, "schema browser" link and see if MaxDoc and NumDocs are wildly different. Is there any chance that more than one process is writing to your index?

Once upon a time i had a usecase where i was indexing product data, and in thta product data a null price ment not currently for sale, but "0" was a legal price for products that were being given away free. i had a similar requirement that the default sort should be based on price, but "free" products should come last ... except if the user explicitly said "sort by price". what i did was to index a "hasPrice" field that was true if the price field existed and was non-zero. my default sort was "hasPrice desc, price asc" but if the user clicked "sort by price" it was "price asc" that might give you ideas about your own usecase. -Hoss

Tokenizing Chinese & multi-language search
Hi, I remember reading in this list a while ago that Solr will only tokenize on whitespace even when using CJKAnalyzer. That would make Solr unusable on Chinese or any other languages that don't use whitespace as separator. 1) I remember reading about a workaround. Unfortunately I can't find the post that mentioned it. Could someone give me pointers on how to address this issue? 2) Let's say I have fixed this issue and have properly analyzed and indexed the Chinese documents. My documents are in multiple languages. I plan to use separate fields for documents in different languages: text_en, text_zh, text_ja, text_fr, etc. Each field will be associated with the appropriate analyzer. My problem now is how to deal with the query string. I don't know what language the query is in, so I won't be able to select the appropriate analyzer for the query string. If I just use the standard analyzer on the query string, any query that's in Chinese won't be tokenized correctly. So would the whole system still work in this case? This must be a pretty common use case, handling multi-language search. What is the recommended way of dealing with this problem? Thanks. Andy
Re: stopFilterFactor and SnowballPorterFilterFactory not work for Spanish

Re: Sorting on multiValued fields via function query
Hi Harish. Did sorting on multiValued fields actually work correctly for you before? I'd be surprised if so. I could be wrong but I think you previously always got the sorting affects of whatever was the last indexed value. It is indeed the case that the FieldCache only supports up to one indexed value per field. Recently Hoss added sanity checks that you are seeing the results of: https://issues.apache.org/jira/browse/SOLR-2339 You might want to comment on that issue with proof (e.g. a simple test) that it worked before but not now. ~ David - Author: https://www.packtpub.com/solr-1-4-enterprise-search-server/book -- View this message in context: http://lucene.472066.n3.nabble.com/Sorting-on-multiValued-fields-via-function-query-tp2681833p2685485.html Sent from the Solr - User mailing list archive at Nabble.com.
SOLR DIH importing MySQL "text" column as a BLOB
I've a column for posts in MySQL of type `text`, I've tried corresponding `field-type` for it in Solr `schema.xml` e.g. `string, text, text-ws`. But whenever I'm importing it using the DIH, it's getting imported as a BLOB object. I checked, this thing is happening only for columns of type `text` and not for `varchar`(they are getting indexed as string). Hence, the posts field is not becoming searchable. I found about this issue, after repeated search failures, when I did a `*:*` query search on Solr.

Re: Problem with field collapsing of patched Solr 1.4
Kai, try SOLR-1086 with Solr trunk instead if trunk is OK for you.

Re: Tokenizing Chinese & multi-language search
Hi Otis, It doesn't look like the last 2 options would work for me. So I guess my best bet is to ask the user to specify the language when they type in the query. Once I get that information from the user, how do I dynamically pick an analyzer for the query string?

Stemming question
When I use the Porter Stemmer in Solr, it appears to take works that are stemmed and replace it with the root work in the index. I verified this by looking at analysis.jsp. Is there an option to expand the stemmer to include all combinations of the word? Like include 's, ly, etc? Other options besides protection? Bill
Re: noobie question: sorting
Hi. Where did you find such an obtuse example?
Recently, Solr supports sorting by function query. One such function is
named "query" which takes a query and uses the score of the result of that
query as the function's result. Due to constraints of where this query is
placed within a function query, it is necessary to use the local-params
syntax (e.g. {!v=...}) since you can't simply state "category:445". Or,
there could have been a parameter dereference like $sortQ where sortQ is
another parameter holding category:445. Any way, the net effect is that
documents are score-sorted based on the query category:445 instead of the
user-query ("q" param). I'd expect category:445 docs to come up top and all
others to appear randomly afterwards. It would be nice if the sort query
could simply be "category:445 desc" but that's not supported.
Complicated? You bet! But fear not; this is about as complicated as it
gets.
