hi all I noticed that there are plenty *PerThread classes in the trunk http://svn.apache.org/repos/asf/lucene/dev/trunk/ while in the realtime_search version http://svn.apache.org/repos/asf/lucene/dev/branches/realtime_search/ the *PerThread classes are gone! this just confused me, cos I'm new here.
what's the purpose of such a design?what's the advantage? any issues refer to this ?? any suggestion or references are appreciated! regards. xu
