Description

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:

<str name="rawquerystring">(*:*)</str>
<str name="parsedquery">(+DisjunctionMaxQuery((text:*\:*)))/no_coord</str>
<str name="parsedquery_toString">+(text:*\:*)</str>
<str name="QParser">ExtendedDismaxQParser</str>

Some variations I tried:

<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>
