Search with less backslash.
Follow the documentation of your favorite plugin manager.
Example:
nmap g/ <Plug>(modesearch-slash)
nmap g? <Plug>(modesearch-question)
cmap <C-x> <Plug>(modesearch-toggle-mode)
You can also start searching with a fixed mode with the following mappings:
" Always starts in 'rawstr' mode
nmap g/ <Plug>(modesearch-slash-rawstr)
" Always starts in 'regexp' mode
nmap g? <Plug>(modesearch-question-regexp)
