Thank you so much Shalin. Yes that would reduce the memory requirement at run time.But my next question, Is the "firstSearcher" doing this I mean due to which it tries to find the "Max value of version" and for that it it has to do the un-inversion.  Thanks and Regards,Sanjay Dutt On

Re: _version_ taking too much memory
