Sometimes a topic whose name is a prefix for a lot of other topics has a lower score than the other topics and thus doesn't appear in the search. The trouble is that you can't narrow the competition by typing more stuff because you've already typed all the stuff so the topic is not findable at all via typeahead.
To some extent this can be addressed by playing with the score, but I think the real answer is that an exact hit ought to get a boost in its rank.
