Missing equals and hashcode preventing the re-use of SharedFieldSortComparator
------------------------------------------------------------------------------

                 Key: JCR-787
                 URL: https://issues.apache.org/jira/browse/JCR-787
             Project: Jackrabbit
          Issue Type: Bug
          Components: core
    Affects Versions: 1.2.3
            Reporter: David Johnson
            Priority: Minor


As briefly mentioned in the dev email list, improperly implemented (i.e., 
missing - using the default Object implementation) equals and hashcode in 
SearchIndex.java prevents the reuse of a SharedFieldSortComparator between 
different queries when nothing has changed in the repository.  In tests, this 
appears to have a fairly significant negative performance impact.

Please see the following for the correct code:
