Subject Re: Realtime Search for Social Networks Collaboration
Date Thu, 04 Sep 2008 13:08:26 GMT
Hello Jason,
I have been trying to do this for a long time on my own. keep up the good
work.

What I tried was a document cache using apache collections. and before a
indexwrite/delete i would sync the cache with index.

I am waiting for lucene 2.4 to proceed. (query by delete)

Best.
