Description

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:

"debug": {
   "rawquerystring": "*:*",
   "querystring": "*:*",
   "parsedquery": "(+MatchAllDocsQuery(*:*))/no_coord",
   "parsedquery_toString": "+*:*",
   ...
}

But with the query (*:*) the Edismax query parser returns a DisjunctionMaxQuery like shown in the following json:

"debug": {
   "rawquerystring": "(*:*)",
   "querystring": "(*:*)",
   "parsedquery": "(+DisjunctionMaxQuery((text:*\\:*)))/no_coord",
   "parsedquery_toString": "+(text:*\\:*)",
   "explain": {},
   "QParser": "ExtendedDismaxQParser",
   ...
}
