Subject [jira] Commented: (LUCENE-520) Ability to abort hit collection
Date Thu, 16 Mar 2006 17:34:58 GMT
    [ http://issues.apache.org/jira/browse/LUCENE-520?page=comments#action_12370722 ] 

Doug Cutting commented on LUCENE-520:
-------------------------------------

Yonik: yes, pulling is a great idea!

Currently one can only create a Scorer given an IndexReader.  If you're using IndexSearcher,
finding the IndexReader is not a problem, and if you're using a non-distributed MultiSearcher
then you can instead use a MultiReader.  Things are only problemmatic if you try to use a
RemoteSearchable.  But both pulling and hit collectors are antithetical to distributed search,
so this should not be a problem in practice.

> If the HitCollector.collect method returned a boolean value rather than void, this value
could be used to determine whether any further hits should be reported. This would speed up
things a bit when all you need is a confirmation that a query produces some hits (e.g. for
generating suggestions).
