[Q] : Search performance

[Emmanuel <e allaud wanadoo fr>]

	Hi all,
I had a look at the balsa-index code : I saw that we now use a hash table 
to handle the search function. The problem I see with that is that we must 
test all messages whereas we're just looking for the next or previous one 
matching the condition. This is particularly suboptimal if you have a big 
mailbox and you're looking for a susbstring contained in the message body.
I think we should just test one by one.
Bye
