Typeahead.js only matches beginning of the word

[vaclavgreif]

I'm using a code very similar to the examples:

var events = new Bloodhound({
    datumTokenizer: Bloodhound.tokenizers.obj.whitespace('name'),
    queryTokenizer: Bloodhound.tokenizers.whitespace,
    limit: 100,
    prefetch: {
        url: Ajax.pluginurl + 'json/events.json',
        ttl: 1
    }
});

events.initialize();

initialize_events_typeahead ();

function initialize_events_typeahead () {
    $('.event_name').typeahead(null, {
        name: 'event',
        displayKey: 'name',
        source: events.ttAdapter(),
        templates: {
            empty: [
                '<div class="empty-message">',
                Ajax.no_results_found,
                '</div>'
            ].join('\n'),
            suggestion: function(data){
                return '<p><strong>' + data.name + '</strong> - ' + data.description + '</p>';
            }
        },
        engine: Hogan
    });

However, this code matches only the beginning of the words, while in the examples it matches also the middle of the words.

Am I missingf something? I also created a stackoverflow question, with answer explaining what's going on: http://stackoverflow.com/questions/23448193/typeahead-js-only-matches-beginning-of-the-word/23619380

I have written failing unit tests to prove this. Modifying the search algorithm to make it work for searching in the middle of words however is beyond the scope of what I'm comfortable with unless someone from the core team wants to provide advice or confirmation that this is something that should be done.
