jcr:like() does not scale well on large value ranges
----------------------------------------------------

         Key: JCR-196
         URL: http://issues.apache.org/jira/browse/JCR-196
     Project: Jackrabbit
        Type: Improvement
  Components: query  
 Environment: svn revision: 239389

    Reporter: Marcel Reutegger
 Assigned to: Marcel Reutegger 
    Priority: Minor
     Fix For: 1.0


There are two major issues with the current WildcardQuery implementation:

1) A wildcard expression is restricted to match at most 1024 terms, otherwise a TooManyClauses
exception is thrown. Similar to the RangeQuery issue: JCR-111
2) The enumeration over the terms that match the wildcard pattern is slow
