Title: added search-highlight-persist-mode

This extension will make isearch and evil-ex-search-incremental (the "slash search") to highlight the search term (taken as a regexp) in all the buffer and persistently until you make another search or clear the highlights with the search-highlight-persist-remove-all command (default binding to C-x SPC). This is how Vim search works by default when you enable hlsearch.
