If your detection algorytims are simple enough, implement them. If you think they will be more expensive them updating all the index, don't detect change.
Another thing to take into account is how much from your index changes. If there are litle docs changing, re-indexing everything will be a waste of processor cycles. 2008/6/10 wojtekpia <[EMAIL PROTECTED]>: > > Hi, > > I'm trying to optimize how I update documents in my index.
