[ http://issues.apache.org/jira/browse/JCR-196?page=all ]
Marcel Reutegger resolved JCR-196:
----------------------------------
Resolution: Fixed
WildcardQuery is now much faster and also works with patterns that match a
large range of terms (e.g. a*).
- The regexp pattern matcher is reused for term compare operations.
- Resolving document id's is done on an unpositioned TermDocs using seek,
instead of acquireing an instance for every term that matches.
Implemented in revision: 239404
> jcr:like() does not scale well on large value ranges

> 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
