I know this is going to end up with me looking stupid, but why does this:
...
(re-search-forward "^[a-z]...$")
...
insist on matching the word "Abba" in this word list:
...
abates
abating
Abba
abbe
abbey
...
I would think it would find "abbe".
I'm trying to match non-capitalized, four-letter words, and this is
ticking me off. Please tell me what I'm missing.
Thanks,
Steve T.

Because the variable `case-fold-search' is not set to `nil'. Read about
search and case in info. (C-h i mem [ret] msea [ret] msea [ret])
Newbies should really make friends with the info pages.

Interactive searches are, by default, case-insensitive. There's some
option somewhere you can set to change this. Or, better, to set it on a
case by case basis (pun intended), type M-c whilst entering your search
string.

(like "aa"), remove half of them (leaving, say, "a").

Only if you enter lower case only. If you enter any
upper case character, then case does matter.

which others have already suggested.

There is no M-c in isearch-mode-map. Typing M-c will
knock you out of isearch mode and capitalize whatever
character point is on.

Note that the OP used a non-interactive search, where the presence
of capital letters in the search string has no effect.
