[jira] [Comment Edited] (SOLR-11156) Edismax query parser fails to parse q=(*:*)

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

With 7.2.1, on the default configset and querying with defType=edismax, I see similar behavior when the *:* query is wrapped in parentheses:

{noformat}
  "debug":{
    "rawquerystring":"(*:*)",
    "querystring":"(*:*)",
    "parsedquery":"+DisjunctionMaxQuery((_text_:*\\:*))",
    "parsedquery_toString":"+(_text_:*\\:*)",
    "explain":{},
    "QParser":"ExtendedDismaxQParser",
{noformat}

I'm not really sure whether this should be considered a bug or not.  The lucene parser handles it like you're expecting, and there's a strong argument that edismax should correctly handle virtually anything the lucene parser can.

I'm pretty sure that the reason this fails is that the \*:\* query is special syntax, and it only gets correctly interpreted if the entire query clause is *exactly* those three characters.  By enclosing it in parentheses, the query clause does not precisely match the special syntax.

> 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}
