In order to have my vim text always bold, I found this config in stackoverflow:
:hi MyGroup cterm=bold
:match MyGroup /./
But somehow, it has messed up search highlighting. It is no longer highlighted, but it shouldn't have any effect on that, since it is only changing the cterm property, and not ctermfg/ctermbg.
I thought if I added the following I would fix it, but it didn't:
:hi Search ctermbg=yellow ctermfg=black term=bold cterm=bold
