Subject RE: document delete after reader.close()
Date Mon, 09 Jul 2007 13:03:27 GMT
Hi Erick,

thanks for your help, this was the solution: Connectors are pooled
resources and i kept always the same reader for all 
connections: bad idea. They never see updates in the index for that
reason. Now i close the readers and everything
is ok.

Warning, I don't know much about JCA Connector.

That said, index modifications aren't visible to a searcher until the
*searcher* is closed and re-opened. Which sounds suspiciously like what
would happen when the thread terminates.

This may be totally off base, but sounds like a place to look...

Best
Erick
