Tips of Git

Disable git branch filter by less

git config --global pager.branch false

Search File Contains Both Pattern in Current Work Directory

git grep --all-match -l --no-index -e 'pattern1' -e 'pattern2'

--all-match means that a file must contains pattern1 and pattern2.
-l means list matched files instead of lines
--no-index only searches current working-set, history not searched.

The confusing part is --or, --and work for single line, not the whole file,
--all-match works on whole file.
