Yes, tying the highlighter code into htsearch is very simple. Writing the
highlighter script itself is the tricky part. It would have to fetch
the document (which may be on another server - wget may be useful
for this), and essentially parse it to highlight all the words (or
variations, e.g. fuzzy matches - maybe using WORDS and LOGICAL_WORDS),
avoiding highlighting text within HTML tags. There was a thread on this
list a few month ago about implementing this, and someone was going to
contribute whatever he developed, but I don't recall hearing any further
news about it.
