Docstring based search for ac-isearch #234
I found myself wanting to filter completion results by docstring, and thought this might be useful functionality for others too. It looks like it needs to be provided by popup-el, so I have suggested a patch for popup-el, and a sample defun for invocation w/auto-complete.
I am not sure if it should be in popup.el. For such complex search I think it is a job for helm. See: https://github.com/yasuyk/ac-helm
When the list is large, and if you want to search docstring, you would need some kind of async search to make isearch responsive. Async search is already implemented in helm. So why not use it?
