- Use chained strings.Contains instead of a regex for
blacklistCandidatesRegexp, as this is a bit faster
- Simplify a Find.Each.Remove to Find.Remove
- Don't concatenate id and class for removeUnlikelyCandidates, as it makes no
sense to match on overlaps. It might also marginally improve performances, as
regex now have to run on two strings separately, instead of both.
- Add a small benchmark
- Replace a completely overkill regex
- Use `.Remove()` instead of a hand-rolled loop
- Use a strings.Builder instead of a bytes.NewBufferString
- Replace a call to Fprintf with string concatenation, as the latter are much
faster
- Remove a superfluous cast
- Delay some computations
- Add some tests
