Should be doable. There were bugs with restrict and exclude in the older
betas, but by 3.1.2 I'm pretty sure they were fixed. I think all the bugs
in the StringMatch class were fixed by then too. These are simple text
strings, not REs or wildcards. The StringMatch class which is used for
these does substring matching, but allows multiple substrings in the given
patterns. You can separate these by "|" characters in the parameter value,
or define multiple input parameter values for restrict or exclude.
I'm not sure what you mean by "mutually exclusive". htsearch checks the
restrict parameter first, if one is given, and if the url doesn't match
it's rejected right away. If it passes this test, then htsearch checks
the exclude parameter, if one is given, and if the url DOES match, it's
rejected, otherwise it's accepted. So, if both restrict and exclude are
specified, the URL must match the restrict value(s) and not the exclude
value(s).
E.g.:
<input type="hidden" name="restrict" value="journal">
<input type="hidden" name="exclude" value="abstract">
should reject /journal/abstract98 but accept /journal/march98.
