Dear Andrzej Bialecki
Can we change the field name in *.fnm directly by hand?

Might another option be to wrap IndexReader?
Something similar to this in principle:

I could come up with a patch if many are interested in this.
What do you like be the best : patching QueryParser ,or a new
QueryParser subclass ?

10 updates per minute is not very much? Why not invalidate your used reader
after every commit, and reopen it? If your index is really big, you might want
to reopen it fewer times, but this is very simple to do (reopen every x updated
times)

There's nothing in the "complex" solution that
has anything to do with recreating the index. The RAMDir
is really the delta between the FSDIr and the updates.
Keeping it all in RAM really consists of reading the FSDIR
into RAM and updating both.

I'm not reindexing the entire index. I'm just commiting the updated. But I'm
not sure how it would affect performance to commit in real time. I think
right now I have like 10 updated per minute.

There are several approaches. First, is your index small
enough to fit in RAM? You might consider just putting it all in
RAM and searching that.
A more complex solution would be to keep the increments
in a separate RAMDir AND your FSDir, search both and
keep things coordinated. Something like

Thats exactly what I do. The moment something is added to the database , I
add it to the lucene index of the user. Upon new account creation, open a
new lucene index for this new user. Whenever something is uploaded, just add
it to the index.
