This causes the HistoryQuickProvider to inherit this as well.  That's probably
problematic as I believe deleting matches there, while desirable, will require
additional bookkeeping.  You should probably scan that file or talk to mrossetti
so you can write an override in that class that calls this function and also
performs the additional work.
