Subject Re: Java Heap Space -Out Of Memory Error
Date Tue, 04 Sep 2007 14:08:12 GMT

Hi testn,
           i index the dateSc as 070904(2007/09/04) format.i am not using
any timestamp here.how can we effectively reopen the IndexSearcher  for an
hour and save the memory because my index gets updated every minute.
