Todd Feak commented on SOLR-805:
--------------------------------
I'm not sure if this will help with the decision or not, but I should clarify.
This problem was not specifically with DisMax queries, though that's what I
initially thought. It's with any query that would contain a MultiPhraseQuery
within it. According to Yonik in the linked in bug, the SynonymFilter could
inject this on a standard query. So, this problem isn't limited to DisMax, but
it also may not encompass *all* DisMax queries.
> DisMax queries are not being cached in QueryResultCache

> Key: SOLR-805
> URL: https://issues.apache.org/jira/browse/SOLR-805
> Project: Solr
> Issue Type: Bug
> Components: search
> Affects Versions: 1.3
> Environment: Using Sun JDK 1.5 and Solr 1.3.0 release on Windows XP
> Reporter: Todd Feak
> Priority: Critical
> Fix For: 1.4
>
>
> I have a DisMax Search Handler set up in my solrconfig.xml to weight results
> based on which field a hit was found in. Results seem to be coming back fine,
> but the exact same query issued twice will *not* result in a cache hit.
> I have run far enough in the debugger to determine that the hashCode for the
> BooleanQuery object is returning a different value each time for the same
> query. This leads me to believe there is some random factor involved in it's
> calculation, such as a default Object hashCode() implementation somewhere in
> the chain. Non DisMax queries seem to be caching just fine.
> Where I see this behavior exhibited is on line 47 of the QueryResultKey
> constructor. I have not dug in far enough to determine exactly where the
> hashCode is being incorrectly calculated. I will try and dig in further
> tomorrow, but wanted to get some attention on the bug.
