Some others may have a better way, but here's what I did and it yielded pretty good results -- and I also selected "match as a phrase" each time:
I typed lime followed by a comma (,) Ê-- lime,
I typed lime followed by a period (.) -- lime.
Note: ÊYou will get instances of the word "sublime", but not so very many as to be a nuisance.
I typed lime followed by a dash (-) -- lime-
I typed a comma then space then the word lime -- , lime
I typed the word limes
See if this gives you what you want, dcampen.
