Comment 2 for bug 681035

I am not sure how we would do that with vocabularies, they return one set of data. The picker could be reimplemented to do an exact look + a search as we do on global search. hmm. Doing so would fix several related vocabulary/picker bugs where exact matches are not top listed (bug 419531). Worse still users get timeouts search for terms that do have an exact match (bug 541979).
