We are going to explore the elisp source code of helm and ido mode, to see how they implement fuzzy matching.
First, we write a emacs command, that lets user choose from potentially thousands of academic phrases. Using ido mode's character based fuzzy matching. 10 minutes.
Helm uses a word based fuzzy matching, and order of words does not matter.
If our elisp exploration of helm source code is successful, we are going to modify our code to use helm's fuzzy matching.
