Truncation can be a mixed blessing, so it is wise to avoid short word stems that could retrieve many different words. If we truncate BEE? to get the word BEE and its plural BEES, we will also retrieve BEEF, BEFFALO, BEER, BEEN, BEETHOVEN, and many other words.

A good general rule is to truncate word stems having at least four characters.
