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


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.
