Hi Siraj, Lucene's MemoryIndex can be used to serve this purpose.
>From ><http://lucene.apache.org/java/3_0_1/api/contrib-memory/org/apache/lucene/index/memory/MemoryIndex.html>: [T]his class targets fulltext search of huge numbers of queries over comparatively small transient realtime data (prospective search). MemoryIndex can only hold one document at a time. See also Lucene's InstantiatedIndex, which can hold more than one document at a time: <http://lucene.apache.org/java/3_0_1/api/contrib-instantiated/org/apache/lucene/store/instantiated/InstantiatedIndex.html> Steve On 05/17/2010 at 4:38 PM, Siraj Haider wrote: > Hello there, > In oracle text search there is a feature to reverse search using > ctxrule.
