Sorry, I let this message through forgetting that the allow / accept

Seems worth mentioning in partial response to this thread's topics that
(almost) regardless of index strategy, lucene performance hinges on number
of matched documents per query, not total docs in index. There are other
mitigating factors (disk type, ram size, etc), but worst case performance

In my experience, reopen will find all changes on an index, whether it was
modified by the same process or not. If you're replicating over a network,
you might need some barrier / lock around the reopen call to make sure the
replicated index is complete. Obviously with something as fickle as a

One way to do this is to create an Analyzer and Tokenizer that are
used on both index and search side. In the tokenStream method, you
return a new normalizing tokenizer; in the Tokenizer, you override the
normalize method to ignore apostrophes.

For what it's worth, I've seen this happen too (using the stock Lucene
3.3 Java APIs), but it requires me to index many millions of
documents, and doesn't start being a really big problem until the
indexes get to be closer to 250GB in size. When they reach around 1TB,
it will take around an hour fo
and
perhaps my hackish solution will work for you (if you're not already
doing this). But indeed on searches returning several million records,
it's kind of silly to keep spinning.

I have my own collector, but implemented this functionality by running
the search in a thread pool and terminating the FutureTask running the
job if it took longer than some configurable amount of time. That
seemed to do the trick for me. (In my case, the IndexReader is
