I squat a fraction of mailboxes each night using:
squatter -s -m 0 -M 7
would update the squat indexes for 1 in 7 mailboxes, based on modulo
arithmetic on the mailbox UniqueID.
squatter would really benefit from incremental updates. At the moment a
single new message in a mailbox containing 20k messages causes it to read
in all the existing messages in order to regenerate the index.
Unfortunately, the code is rather impenetrable. I infer that it is
collecting information about adjacent characters in the message body.
Presumably a 5 character search term provides 4 required pairing as a
prefilter from the squat engine before message by message search kicks in.
