I have the /i qualifier switched for all preg match and replace calls.

apples & oranges would need to be entered as regex: apples|oranges

can this be because you apply wordboundary character \b ?

I have no option top show active markup directives and active markup
expressions, since the results were too horrible.
Either lines containing directives are ignored, which will give
perhaps some missing results, or the directives and expressions are
shown as code. The latter is the default and looks acceptable when
doing for instance searches in the PmWiki documentation.

I do not block it, but show it as code, with the term being
highlighted. Or lines with markup directives are cut and not leading
to results.

By far the most tricky bit is how to treat various directives, and how
to get the highlight right when the term is in a code escape markup
like [@ ... term ...@] or [= ...term ...=] or some worse cases.

If you look at extract.php function TextExtract case 'code'
you see a number of replacements are happening for various reasons to
defuse some active markups. It still fails in a few cases, but works
for most. PmWiki.ChangeLog is a great page to use as a source for
testing, full of weird markup!
