Subject [jira] [Updated] (SOLR-3741) ExtendedDismaxQParser (edismax) does not obey q.op for queries with operators
Date Sat, 08 Sep 2012 00:39:07 GMT


Hoss Man updated SOLR-3741:

    Fix Version/s:     (was: 4.0)
                       (was: 3.6.2)

removing fixVersion=4.0 since there is no evidence that anyone is currently working on this
issue.  (this can certainly be revisited if volunteers step forward)

> For a query such as "cat dog OR (fox bat fish)" with &q.op=AND, the default query
operator remains "OR" for the entire query. This is not documented behavior and rather surprising.
> This happens because edismax only simulates the default operator by forcing "mm" (minMatch)
to 100% for the top-level BooleanQuery alone, but only if there are NO explicit operators
> One solution is for edismax to always set the default query operator when calling the
classic Lucene query parser, or at least when q.op=AND.
