Reusing same searcher in Solr?

[Shawn Heisey]

I was reading Mike McCandless' blog and came across this post:

Is this kind of functionality available in Solr?  I update my index once 
a minute, so being able to reuse an old searcher for a little while 
would be very interesting.  I do get a little worried about memory usage.

Thanks,
Shawn
