Subject [jira] [Created] (SOLR-3729) ExtendedDismaxQParser (edismax) doesn't parse (*:*) properly

------------------------------------

             Summary: ExtendedDismaxQParser (edismax) doesn't parse (*:*) properly
                 Key: SOLR-3729
                 URL: https://issues.apache.org/jira/browse/SOLR-3729
             Project: Solr
          Issue Type: Bug
          Components: query parsers
    Affects Versions: 4.0-BETA
            Reporter: Jack Krupansky


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

<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>
