Re: Boosting fields in SOLR using Solrj
Thanks Ryan. I created a second requestHandler, which works fine in the browser. In solrj, how do I tell the SolrQuery which request handler to use? It always seems to default to another requestHandler. -- View this message in context: http://lucene.472066.n3.nabble.com/Boosting-fields-in-SOLR-using-Solrj-tp3939789p3945496.html Sent from the Solr - User mailing list archive at Nabble.com.

I finally figured this out.

Re: Boosting fields in SOLR using Solrj
I would suggest debugging with browser requests -- then switching to Solrj after you are at 1st base. In particular, try adding the debugQuery=true parameter to the request and see what solr thinks is happening. The value that will work for the 'qt' parameter depends on what is configured in solrconfig.xml -- I suspect you want to point to a requestHandler that is configured to use edismax query parser. This can be configured by default with: lst name=defaults str name=defTypeedismax/str /lst ryan On Wed, Apr 25, 2012 at 3:57 PM, Joe joe.pol...@gmail.com wrote: Hi, I'm using the solrj API to query my SOLR 3.6 index.

What you're searching is the text title:apples oranges content:apples oranges. Depending on your analyzer chain, it might be that title:appes and content:apples are kept as one token, so nothing is found because there's no such token in the index. Why don't you simply query for apples oranges? That's how (e)dismax is made for. Have a deeper look at http://wiki.apache.org/solr/DisMax. BTW, if you used the above query in a Lucene parser, it would look for apples in title and content field, but look for oranges in your default search field. This is because you didn't quote apples oranges. Since you want to use Edismax, you can ignore this, it's just that you current query won't work as expected in both cases. -Kuli
