SearchNotes not finding notes

[hinojojojo]

Hi,
I have been using vim-notes for a while now. I use a git repository to store my notes and sync among computers. I recently set up vim-notes in a new computer, but I cannot make SearchNotes to work on it. Any time I search with any keyword, either a keyword that should be in a note title or listed with @ in a note, SearchNotes returns "No matches". Otherwise, I can access the notes with other commands (e.g. with :RecentNotes, :ShowTaggedNotes) perfectly. What do you think it could be the issue with SearchNotes?
I use neovim, the pluggin is loaded with vimPlug:
Plug 'https://github.com/xolox/vim-notes.git'
Plug 'https://github.com/xolox/vim-misc.git'

and the directory of the notes is set up in the vim.init file:
let g:notes_directories = ['~/Documents/git_repos/vimNotes/']
