             Summary: Edismax query parser fails to parse q=(*:*)
                 Key: SOLR-11156
                 URL: https://issues.apache.org/jira/browse/SOLR-11156
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
          Components: query parsers
    Affects Versions: 5.5.1
         Environment: Solr 5.5.1
            Reporter: Alfonso Noriega Meneses


The Edismax query parser does parse the query {{(\*:\*)}} as a exact text match 
instead of a match all documents.

Setting the debugQuery param to true and the query  {{\*:\*}}  we get this json:
{code}
"debug": {
   "rawquerystring": "*:*",
   "querystring": "*:*",
   "parsedquery": "(+MatchAllDocsQuery(*:*))/no_coord",
   "parsedquery_toString": "+*:*",
   ...
}
{code}

But with the query {{(\*:\*)}} the Edismax query parser returns a 
{{DisjunctionMaxQuery}} like shown in the following json:
{code}
"debug": {
   "rawquerystring": "(*:*)",
   "querystring": "(*:*)",
   "parsedquery": "(+DisjunctionMaxQuery((text:*\\:*)))/no_coord",
   "parsedquery_toString": "+(text:*\\:*)",
   "explain": {},
   "QParser": "ExtendedDismaxQParser",
   ...
}
{code}
