Hi, I am new to edismax, and trying to migrate from dismax to edismax. For the queries with the explicitly quoted sub phrase query, it seems edismax will ignore the quoted one, compared with dismax during the whole query phrase matching process (pf). Here is one example:
For the same query: 2012 "japan airlines" flight status, dismax http://localhost:8983/solr/select?q=2012+"japan+airlines"+flight+status&qf=TTL&pf=TTL&debugQuery=true&defType=dismax outputs: <str name="parsedquery">+((DisjunctionMaxQuery((TTL:2012)~0.1) DisjunctionMaxQuery((TTL:"japan airlin"~3)~0.1) DisjunctionMaxQuery((TTL:flight)~0.1) DisjunctionMaxQuery((TTL:status)~0.1))~3) DisjunctionMaxQuery((TTL:"2012 japan airlin flight status"~3)~0.1)</str> The parsedquery has DisjunctionMaxQuery((TTL:"2012 japan airlin flight status"~3)~0.1). While edismax http://localhost:8983/solr/select?q=2012+"japan+airlines"+flight+status&qf=TTL&pf=TTL&debugQuery=true&defType=edismax outputs: <str name="parsedquery">+((DisjunctionMaxQuery((TTL:2012)~0.1) DisjunctionMaxQuery((TTL:"japan airlin"~3)~0.1) DisjunctionMaxQuery((TTL:flight)~0.1) DisjunctionMaxQuery((TTL:status)~0.1))~3) DisjunctionMaxQuery((TTL:"2012 flight status"~3)~0.1)</str> The parsedquery has DisjunctionMaxQuery((TTL:"2012 flight status"~3)~0.1). So it seems edismax ignores "japan airlines" for the pf matching. This could cause some issues, in that a document with exactly phrase "2012 japan airlines flight status" will have the same relevancy score with another one with two phrases "japan airlines", "2012 flight status" far away. Is this the intended behavior of edismax, or am I missing anything ? Thanks a lot for the help !
