Reduce amount of search highlighting

[randomnetcat]

This should fix the issues with apparently-random characters being highlighted, as described in RHCLOUD-33948.

This one was used before but it has the opposite problem, Sometimes it just does not highlight exact matches at all.

Lovely. I've reverted back to Levenshetin search, fixed a bug in the highlighting code that offset the highlighted portion from where it should be, and also made it only show the lowest-distance matches.
