This is a Gmail-only version of the original mutt-notmuch script.

It will interactively ask you for a search query and then symlink the matching messages to $HOME/.cache/mutt_results.

Add this to your muttrc.

macro index / "<enter-command>unset wait_key<enter><shell-escape>mutt-notmuch-py<enter><change-folder-readonly>~/.cache/mutt_results<enter>" \
        "search mail (using notmuch)"

This script overrides the $HOME/.cache/mutt_results each time you run a query.

Install this by adding this file somewhere on your PATH.

Only tested on OSX Lion.

BSD, short and sweet
