yes, lucene take  an snapshot of the directory and don't see changes
maded after is opened

it's not cheap, so you have to reopen periodically, an for better
performance launch somo queries for warm the caches

in our case, we have 3 index servers, and we send the updates to the
three, so all of them work in parallel and i don't have to worry about
copyng files. this is another approach tha you can use if the number
of search servers is small.
