That's your call. Find By Content cannot see inside files it has not indexed, so if you don't index frequently enough you'll find that you're working on out-of-date data. But it does take time -sometimes a long time- so doing it too often is a pain.
A good medium is to do it once a week. I think the system may actually do this for you, as part of the system maintenance scripts.
