Now gist.github.com supports search. So you can search your gist. I use #hashtag in description, so I
can search my gist by tags via user:myusername #tag.
For offline usage, I cloned all my gists. And use find and grep to search them. I also search them with gonzui (open source code search engine).
I've written a shell script: gister.sh. I use it to
post gists. It will clone the repo to local and import into csearch automatically after the post.
The script also supports sync all your gists (gister sync).
