My C++ skills are still okay, but I seem to have managed to come up with a wee patch,
that I think is quite useful. If a score is less than or equal to zero, I cannot see
any particular reason for showing it. After all, if the trouble of putting
text_factor:0 has been gone through, why show a result that has matching text in the
BODY section and nowhere else, if the desire is to give it zero weighting?
In Display.cc, in the Display::buildMatchList() section, the line that reads:
matches.Add(thisMatch, url.get());
.. I simply surrounded this condition around it:
if (score > 0) {
matches.Add(thisMatch, url.get());
}
I appear to be getting desirable results. If this will cause any problems elsewhere,
please let me know.

My C++ skills are, umm, okay. :-) But thanks for saving me time, because at least I
know to start in the htsearch/Display.cc.
As for an HTML object/segment having a factor of zero, I think it would make a lot of
sense to have it drop off (if it were the only matching component to the query). I
will keep you informed of my progress or lack thereof.

According to Katherine Porter:

As Geoff mentioned, in 3.2 the *_factor attributes only affect htsearch,
not htdig. In any case (3.1 or 3.2) a factor of 0 just drops the score
of a match to 0, putting the match at the end of the list of results, but
not dropping it off the list. I believe that's the case for both 3.1.x
and 3.2.0bx. Causing 0 scores to remove matches from the results would
be a new feature, I think, because the scores just affect rankings, and
not selection or rejection.

Not all changes are discussed on htdig-general or htdig-dev before
being committed. However, all CVS log entries for committed changes are
posted to htdig-updates. There was a change on Sept. 4 that might have
an effect on score calculations, but nothing that I know of will cause
low or zero scores to be dropped off the result list.

How are your C++ skills? :-) I think this would require changes to
Display::buildMatchList(), in htsearch/Display.cc.
