Typeahead.js & bloodhound caching

Let's imagine that I search for "clean" in an input that is using [login to view URL] for autocompletion. The remote server performs the search and returnes the results. The remote server did a search with mysql LIKE in the form of WHERE x LIKE clean%. So this will return all results for strings starting with clean. Now the user continues typing until cleaning. Since this is an extension to the previous search query clean we could simply look into the previous results and narrow them down to cleaning, that way we could completely avoid an additional request. The project is about creating this functionality.
