-------------------------------------------------------------------
I have an indirect evidence that *:* is given to the analysis chain and the
tokens are concatenated together and fed to DisjunctionMaxQuery. This is not
supposed to be happening, is it? Because my analyzer generates 3 tokens "*",
":", and "*", and reconstruction of the query inserts a space between them, I
am seeing this in debug output (note a space between "*" and ":"):
{noformat}
DisjunctionMaxQuery((body:"* : *"~100^0.5...
{noformat}
If this phenomena is nothing to do with this bug, my apology. I'll file a
separate bug.
This behavior is observed with Solr 3.5.0. I haven't tried Solr 4.0.

> Project: Solr
> Issue Type: Bug
> Components: query parsers

> 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>
