'Query search for matches issue' with Trie data structure

Simply put, this Git source hasn't fixed the issue that could be described as:

With Bloodhound engine data to search for California, we type 'c' and retrieves the state with typeahead (54 states data). but typing 'l', 'i', 'for', 'li',... does not include California as a selective option or even nothing found. [Try it here](http://typeahead.js.org/examples/) with all examples EXCEPT for the very first one.

If your version based off this stale version, please have a look at my raised concern:

If the problem is on Trie data structure, could you change the [node data method](https://github.com/twitter/typeahead.js/blob/7ed93f9759b0eacaaca8d3568ca8087a70d7091a/src/bloodhound/search_index.js#L55) in search_index.js so as to fix it?
