There is a way to prevent typeahead from triggered until a symbol is typed?

Hi, thanks for the work to translate this package to be meteor friendly. However, this is a doubt that I will post here and into the twitter/typeahead project, there is a way to set like: "only fetch results after type X symbol" in addition it would be more powerful if we have a way to scope the source using the trigger symbol like:

• Bring me the tags after type #
• Bring me the users after type @

If there is a way could someone throw me a link here? or a simple example. Otherwise, I will be more than happy to help to do so.
