Subject Sharding of Indexes in clucene
Date Thu, 11 Mar 2010 07:02:06 GMT

Hi,

Does the clucene have the concept of Sharding of Indexes.
How much performance boost it provides in case of searching.Can we mention
to get documents from a perticular shard only, so as to reduce the set of
documents to be searched from.


Regards,
Suman
