We periodically check the database and find new documents. > 1.b) For IndexSearcher, I know I have to reinstantiate it (open it), > but how do I do that while still maintaining current search requests?

And then I swap out the one in RAM. > 2.a) Has anybody done this in an automated efficient way? If so, how? We have done it by maintaining the old index and rebuilding the new index at the same time. And if the new index is successfully built, we switch to the new index and destroy the old one. The software is called DBSight. You are welcome to check it out.
