Yes, the parsing of the keywords input parameter is much more
simple-minded than the parsing of the words input parameter. It only
allows white space (space, tab, newline) as separators, as well as Ctrl-A
which is the separator used for multiple input parameter definitions,
e.g. if you use checkboxes for building keywords input parameters.
There's no configuration option to change this. You need either to
clean up the keywords list you give to htsearch, or you need to modify
htsearch to do better parsing of this parameter. Right now, this is at
line 179 in 3.1.5's htsearch/htsearch.cc:
requiredWords.Create(config["keywords"], " \t\r\n\001");
You'd either need to add all punctuation characters you're likely
to encounter to the list at the right, or you'd need to build up the
StringList some other way.
