Hello, I think you have to issue a phrase query in such a case because otherwise each "token" is searched independently in the merchant field : the query parser splits the query on spaces!
Check the difference between debug outputs when you search for "Jones New York", you'd get what you expected. Hope this helps, -- Tanguy 2012/6/11 Vijay Ramachandran <vijay...@gmail.com> > Hello.

The debugQuery shows that the query splits the words up, like thus: > <str name="parsedquery">+((DisjunctionMaxQuery((summary:jones^2.0 | > title:jones^3.0 | merchant:jones^3.0 | cats4match:jones)~0.1) > DisjunctionMaxQuery((merchant:new^3.0)~0.1) > DisjunctionMaxQuery((summary:york^2.0 | title:york^3.0 | merchant:york^3.0 > | cats4match:york)~0.1))~1) DisjunctionMaxQuery((summary:"jones ? > york"~3^5.0 | title:"jones ? york"~3^10.0 | cats4match:"jones ? > york"~3^5.0)~0.1) ()</str> > > My edismax is configured this: > <requestHandler name="edismax" class="solr.SearchHandler" default="true"> > <lst name="defaults"> > <str name="defType">edismax</str> > <str name="echoParams">explicit</str> > <float name="tie">0.1</float> > <str name="fl"> > dealid,category,subcategory,merchant, merchant_id, title > </str> > <str name="mm">1</str> > <str name="qf"> > cats4match^1.0 merchant^3.0 title^3.0 summary^2.0 > </str> > <str name="pf"> > cats4match^5.0 merchant^10.0 title^10.0 summary^5.0 > </str> > <int name="ps">3</int> > <str name="pf2"> > cats4match^5.0 merchant^10.0 title^10.0 summary^5.0 > title_phrases^10.0 summary_phrases^5.0 > </str> > <str name="pf3"> > cats4match^5.0 merchant^10.0 title^10.0 summary^5.0 > title_phrases^10.0 summary_phrases^5.0 > </str> > <int name="qs">3</int> > <str name="q.alt">*:*</str> > </lst> > </requestHandler> > > > What gives?
