Highlights find upgrade (#11509)

Browse Source 
this PR should close #9105

# Description
I have implemented highlights for find which work for all strings. The
implementation also works for lists, but with exceptions (for example,
it does not work for list of lists). The implementation is also not
implemented for --regex.
