Mike commented on SOLR-2649:
----------------------------
Yeah, I'm seeing this too. A user has reported that they queried:
(internet OR online OR web) "personal jurisdiction"
I have defaultOperator set to AND, so I'd expect the query to get processed as:
(internet OR online OR web) AND "personal jurisdiction"
But it is instead getting processed with an OR statement. I've confirmed this
using debug.
This doesn't seem like ideal functionality for the default operator to work,
except when the user tries to override it in parts of a query. This seems like
more than a minor issue to me.
> MM ignored in edismax queries with operators

> Key: SOLR-2649
> URL: https://issues.apache.org/jira/browse/SOLR-2649
> Project: Solr
> Issue Type: Bug
> Components: search
> Affects Versions: 3.3
> Reporter: Magnus Bergmark
> Priority: Minor
>
> Hypothetical scenario:
> 1. User searches for "stocks oil gold" with MM set to "50%"
> 2. User adds "-stockings" to the query: "stocks oil gold -stockings"
> 3. User gets no hits since MM was ignored and all terms where AND-ed
> together
> The behavior seems to be intentional, although the reason why is never
> explained:
> // For correct lucene queries, turn off mm processing if there
> // were explicit operators (except for AND).
> boolean doMinMatched = (numOR + numNOT + numPluses + numMinuses) == 0;
> (lines 232-234 taken from
> tags/lucene_solr_3_3/solr/src/java/org/apache/solr/search/ExtendedDismaxQParserPlugin.java)
> This makes edismax unsuitable as an replacement to dismax; mm is one of the
> primary features of dismax.
