Queries with conditional field inclusions?
I'm trying to put together a query in Solr that is becoming rather complicated, and I'm not quite sure where to even start. I'm building a directory, which for simplicity sake contains: First Name Last Name Department Name (if faculty / staff) User Types - faculty, staff, student - multivalued. I want one search field to search first, last, and department. I have that working. However, that means you can find students using a first name only search, which isn't exactly desirable, but it is desirable for faculty and staff. So I want: Search Department Name + Last Name every time include First Name if user type in (faculty, staff) or if another token matched last name. So searching for richard would only work for me if I'm marked as faculty or staff. However searching for frovarp richard would limit to my record if I was marked as a student as the frovarp piece would match against last names. Any suggestions or ideas? I'm testing against Solr 4.3.1, but will probably be updating to 4.5.1 anyway. I'm open to multiple cores or searches. I actually have 4 different first and last name fields (full, ngram, two phonetic), so scoring becomes important. Thanks, Richard

I'm not setting the mm parameter or the q.op parameter. All three cores have a defaultOperator of OR. So I don't know where that would be coming from. However, if I specify a mm of 0, it appears to work just fine. I've added it as a default parameter to the select handler. Thanks for pointing me in the right direction. Richard

Term boosting isn't working either, and what I did above just turns everything into an OR query. I did figure out the problem, however. In the core that wasn't working, one of the query field names wasn't correct. No errors were ever thrown, it just made the query behave in a very odd way. I finally figured it out after debugging each field independent of each other.

Try executing your query on the cores with debugQuery=on and compare the parsed results (for this you can probably just ignore the explain bits of the output, concentrate on the parsed query). Okay, for the example core from the project, the query was: test OR samsung parsedquery: +(DisjunctionMaxQuery((id:test^10.0 | text:test^0.5 | cat:test^1.4 | manu:test^1.1 | name:test^1.2 | features:test | sku:test^1.5)) DisjunctionMaxQuery((id:samsung^10.0 | text:samsung^0.5 | cat:samsung^1.4 | manu:samsung^1.1 | name:samsung^1.2 | features:samsung | sku:samsung^1.5))) For my core the query was: frovarp OR fee parsedquery: +((DisjunctionMaxQuery((content:fee | title:fee^5.0 | mainContent:fee^2.0)) DisjunctionMaxQuery((content:frovarp | title:frovarp^5.0 | mainContent:frovarp^2.0)))~2) What is that ~2? That's the difference. The third core that works properly also doesn't have the ~2.
edismax not working in a core
I'm having trouble with edismax not working in one of my cores. I have three cores up and running, including the demo in Solr 3.6 on Tomcat 7.0.27 on Java 1.6. I can't get edismax to work on one of those cores, and it's configured very similar to the demo, which does work. I have different fields, but overall I'm not doing much different. I'm testing using a query with OR in it to try to get a union. On two of the cores, I get the union, on my third one I get a much smaller set than either term should return. If I tell the misbehaving core to have a defType of lucene, that does honor the OR. What could I be possibly missing? Thanks, Richard
Re: Run Solr within my war

My question is more along the lines of how to put the server jars that perform the core functionality and bundle them to start up within a war which is also the application war for the program that will communicate as the client with the Solr server. I could be way wrong, but my interpretation is that EmbeddedSolrServer provides a way to embed Solr into an application without requiring that anything else is running. http://wiki.apache.org/solr/Solrj#EmbeddedSolrServer If you are looking for a method of your application doing SolrJ calls to Solr, without having to install a separate Solr instance, EmbeddedSolrServer would meet your needs. You'd have to use a few other functions to load the core and register it, but it's doable without having anything else running.

How easy/difficult is that to setup? Can anyone with past experience on this topic, please comment. thanks, - Pulkit So basically you're talking about running an embedded version of Solr like the EmbeddedSolrServer? I have no experience on this, but this should provide you the correct search term to find documentation on use. From what little code I've seen to run test cases against Solr, it looks relatively straight forward to get running. To use you would use the SolrJ library to communicate with the embedded solr server. Richard

Text of the document is fairly large. The category of the document changes often while the text remains the same. Search happens on both fields. The problem is, I have to index both the text and the category each time the category changes. The text being large obviously makes this suboptimal. Is there a patch or a tricky way to avoid indexing the text field every time. Sure, make the text field as stored, read the old document and create the new one. Sorry, there is no way to update an indexed document in Solr (yet). Could you use SolrJ to grab a record, convert it over to an input record and update the one field? I suppose Solr would still reindex the whole thing, but at least you wouldn't have to do full pre-processing on the source. Richard
