 **Note**:
 
+- if you set `isNeovim: true`, command like `fixdel` in vimrc which neovim does not support will report error.
 - if you want to speed up index, change `gap` to smaller and `count` to greater, this will cause high CPU usage for some time
 - if you don't want to index vim's runtimepath files, set `runtimepath` to `false` and you will not get any suggest from those files.
