Xapian discuss - Mar 2011 - phrase search highlighting

Hi
Some of my users are very "conservative" as it seems :)

The complained about "not finding anything useful", because the
highlighted sample
was wrongly colored when doing phrase search, e.g. "some word".
So they refused to use web search at all and keep telephoning around.

Not the found phrase was highlighted in one color, but all locations
of these words within the sample in different colors.
"This result is wrong" was their complaint when looking at the sample.

So I had to disable phrase highlighting at all like this:

query:
<!-- highlight only if Query does not contain PHRASE -->
$if{$eq{$substr{$query,0,1},"},$field{sample},$highlight{$field{sample},$terms}}$if{$field{sample},...}

(works only if the phrase is the first term, but that 99.9% the case)

If time permits please adjust omega highlighting for phrases. My time
is currently very limited unfortunately.

You really want $html{$field{sample}} for the first occurrence there,
so that characters get escaped properly ($highlight does this as well
as highlighting).

This (untested) approach should spot any phrase (including ones from
hyphenation, etc):

$if{$find{$list{$querydescription},PHRASE},$html{$field{sample}},$highlight{$field{sample},$terms}}$if{$field{sample},...}

Yes, it would be good to handle this.  Can you open a ticket please?
