If this worked, your recipe would make a nice generic search box.

Who knows how long "Show search terms in context" will remain in the
road map.

But highlighting two different words works, e.g. seperated|underneath.

Another question: How hard would it be to define the extent of the
extract not in paragraphs or lines but in words? Some paragraphs are
too long (e.g. change log, release notes), while others are too short
to give enough context.
