Re: [Evolution] .IBEX file? UPDATE

Ibex files aren't the same type of index that the summary file is. The
summary file has a chunk of data per message that contains info like
subject, to, from, etc. The ibex files are more of a lookup table that
indexes all the words found and which message(s) they were found in.

What I suspect is happening is that when messages are deleted, the code
does not force a re-ibexification of the messages because it'd be
extremely slow to do on large mailboxes. Simply put, this is an

If you are tight on space or you don't search much, then you can always
turn the indexing off. This will make it so that .ibex files will not be
created but, at the same time, searches will be slower if searching on
body content.

Why would the index be close to twice as large as the file it's
indexing? I deleted/expunged many mails from this folder, and the mbox
size went from 3.3M down to the 2.59M you see above. Yet the .ibex file
size stayed the same, at 4M. Wouldn't it have also gone down, since
there was now over 100 emails less to index?

Ok. So after deleting even more email (I'm now down to a mbox size of
2M, from it's original size of 3.3M), I closed Evo, and deleted the
.ibex file.

This .ibex file was 4.4M in size; it never changed size, to reflect the
now smaller size of the mbox.

So, then I restarted Evo, and - as expected - it recreated the .ibex

Note that the size is now only 17% of it's previous size (711,936 v
4,006,400). And, as a side effect, that I've gained 3M disk space. :-)

A suggestion: perhaps a button, or menu item, to "Rebuild index". Looks
like (for now), the .ibex isn't being updated to reflect downward sizing
of mbox files (altho I will admit that this is the only folder I've
tried this experiment on, as of this moment). Manually rebuilding the
index would help to clear out the cruft (a word I've only heard used in
conjunction with Linux, BTW :-).

Perhaps it wouldn't hurt, every now and again, to close Evo, and rm all
the .ibex files, so they could periodically be rebuilt. I'd hate to put
a command like that in a cron script, since Evo might be open and
running when the .ibex files got removed; and I presume that could cause
