I don't think Srini was referring to meta tag keywords either. The "+"
separator seems to imply CGI parameters, so I think you're on the same
wavelength, but the "+" is not required in this context.

Yes, this is correct.

The word length is related to the setting of the minimum_word_length
config attribute, and treating bare numbers as words can be enabled via
the allow_numbers attribute. The problem seems to creep in when there
is no valid search word in the "words" input parameter. You didn't
mention which version of htsearch you were running, but there's a patch
for 3.1.5 that fixes this problem, as well as adding a new option to
make htsearch use OR rather than AND for keywords. Find it at

That's only true when you supply the keywords as parameters within a URL.
Spaces are perfectly alright in the value field inside a search form, and
a "+" in that context would be encoded when passed as a CGI parameter so
it would remain a "+", and not get interpreted as a space, when htsearch
looks at the parameter.
