count
openFDA's most valuable feature: aggregate over any dataset by a field to get a top-terms histogram (returns `results: [{term, count}]` instead of records). Use the '.exact' field suffix to count whole phrases. Example: endpoint 'drug/event', field 'patient.reaction.reactionmeddrapt.exact', search 'patient.drug.medicinalproduct:"aspirin"' → the most common reactions reported for aspirin.

Use the named search tools for the common datasets; use this for everything else or for advanced queries. openFDA REST API.
