IndexSearcher usage and caching?

[Joel Shellman <jo...@ikestrel.com>]

I'm working on a document management system using lucene to search 
through all the documents.

This means that I'll be adding/updating/deleting documents at the same 
time searches are going on.

I thought to create an IndexSearcher and reuse it throughout, but that 
doesn't seem to work. If I do a search, then add a document, and do 
another search with the same IndexSearcher, it won't find the newly 
added document.

I'd rather not have to create a new IndexSearcher for every query... do 
I have to?

Thanks,

-joel shellman

Cache/reuse your IndexSearcher.
On every search, check if the index has changed (there are methods for
that).
If it has changed, create a new IndexSearcher and assign it to your
IndexSearcher variable, and do not close the old IndexSearcher, just in
case something is still using it.
