Hoss Man updated SOLR-3729:
---------------------------
Fix Version/s: (was: 4.0)
Assignee: (was: Hoss Man)
After reviewing the patch a bit, i'm skeptical of this regex ... in particular
it drasticaly changes the behavior in any case where "\*\:\*" is embedded in a
longer string, ala...
http://localhost:8983/solr/select?defType=edismax&debugQuery=true&q=foo*:*bar
There may be other impacts that are less obvious.
Given that this bug seems to have been around for a while, i don't think we
should rush a fix like this into 4.0 ... i'd rather leave it alone until we
find a more robust solution.

> I just happen to notice that (\*:\*) is not parsed properly by the edismax
> (ExtendedDismaxQParser) query parser in 4.0-beta. It appears to require
> spaces before and after the \*:\*, otherwise it treats the colon as part of a
> wildcard term (see the escaping below). I haven’t tried other releases yet.
> My original query:
> http://localhost:8983/solr/select/?debugQuery=true&q=(*:*)&defType=edismax
> Produces this:
> {code}
> <str name="rawquerystring">(*:*)</str>
> <str name="parsedquery">(+DisjunctionMaxQuery((text:*\:*)))/no_coord</str>
> <str name="parsedquery_toString">+(text:*\:*)</str>
> <str name="QParser">ExtendedDismaxQParser</str>
> {code}
> Some variations I tried:
> {code}
> <str name="rawquerystring">( *:*)</str>
> <str name="parsedquery">(+DisjunctionMaxQuery((text:*\:*)))/no_coord</str>
> <str name="parsedquery_toString">+(text:*\:*)</str>
>
> <str name="rawquerystring">(*:* )</str>
> <str name="parsedquery">(+DisjunctionMaxQuery((text:*\:*)))/no_coord</str>
> <str name="parsedquery_toString">+(text:*\:*)</str>
>
> <str name="rawquerystring">( *:* )</str>
> <str name="parsedquery">(+MatchAllDocsQuery(*:*))/no_coord</str>
> <str name="parsedquery_toString">+*:*</str>
>
> <str name="rawquerystring">(*:* -fox)</str>
> <str name="parsedquery">
> (+(DisjunctionMaxQuery((text:*\:*))
> -DisjunctionMaxQuery((text:fox))))/no_coord
> </str>
> <str name="parsedquery_toString">+((text:*\:*) -(text:fox))</str>
>
> <str name="rawquerystring">( *:* -fox)</str>
> <str name="parsedquery">
> (+(MatchAllDocsQuery(*:*) -DisjunctionMaxQuery((text:fox))))/no_coord
> </str>
> <str name="parsedquery_toString">+(*:* -(text:fox))</str>
> {code}
