It would also be good to have an option to not stem at all (for a lookup, and I assume that would mean building two databases for the search, one with words stemmed, and one with just the words as they appear.)
I know that often when I do a search, the reason is that I remember some phrase from a man page I read in the past, but don't remember which man page I read it in ... when I do a search like that, I want to look for exactly what I recall reading, so if, for example, I remember "compare directories" or something like that, and I search for "directories" I want to see only entries that exactly match that, and I do not want to get told of some man page just because it has "directory" in it. I also don't mind doing two or three searches with slightly different keys, if I don't find what I am looking for on the first (or second) attempt. That's usually far better than being overwhelmed with dozens (or hundreds) of matches that are "kind of like" what I was looking for in the expectation that one of them will be what I really wanted - if I have to send the output of "man -k" through grep, I consider that a failure... kre
