Jan Høydahl updated SOLR-8812:
------------------------------
Attachment: SOLR-8812.patch
Attaching patch with a failing test case. It is quite shocking that we apparently did not have test coverage of basic OR with q.op=AND already??

> Key: SOLR-8812
> URL: https://issues.apache.org/jira/browse/SOLR-8812
> Project: Solr
> Issue Type: Bug
> Components: query parsers
> Affects Versions: 5.5

> The edismax parser ignores Boolean OR in queries when q.op=AND. This behavior is new to Solr 5.5.0 and an unexpected major change.
> Example:
> "q": "id:12345 OR zzzzzzzzzz",
> "defType": "edismax",
> "q.op": "AND",
> where "12345" is a known document ID and "zzzzzzzzzz" is a string NOT present in my data
> Version 5.5.0 produces zero results:
> "rawquerystring": "id:12345 OR zzzzzzzzzz",
> "querystring": "id:12345 OR zzzzzzzzzz",
> "parsedquery": "(+((id:12345 DisjunctionMaxQuery((text:zzzzzzzzzz)))~2))/no_coord",
> "parsedquery_toString": "+((id:12345 (text:zzzzzzzzzz))~2)",
> "explain": {},
> "QParser": "ExtendedDismaxQParser"
> Version 5.4.0 produces one result as expected
> "rawquerystring": "id:12345 OR zzzzzzzzzz",
> "querystring": "id:12345 OR zzzzzzzzzz",
> "parsedquery": "(+(id:12345 DisjunctionMaxQuery((text:zzzzzzzzzz))))/no_coord",
> "parsedquery_toString": "+(id:12345 (text:zzzzzzzzzz))"
> "explain": {},
> "QParser": "ExtendedDismaxQParser"
