benson margulies commented on LUCENE-731:
-----------------------------------------

Which means that I have to constantly close and recreate the searcher, as well? How is this 'simultaneous' .. ok, I see, you can search for what was stored up until the last call to close().

Gosh, it would be nice if there were a communications mechanism so that a call to 'commit' on a writer just caused extant searchers to catch up. And what if the index is so large that the searcher can't have loaded it entirely into memory? At very least, a flush() that saved recreation would seem helpful.

Is the pattern to create searchers with short lifetimes? That seems like an expensive proposition.

> The FAQ says that you can index and lookup simultaneously. I tried what appeared to be the simplest possible implementation of that, and the searcher never finds anything. I will attach a junit test.
> If the code is working as designed, please consider this a bug in the FAQ or some other doc that there is no pattern given for how to do this.
