openFDA / Count drug adverse events by reaction, drug or other field

Totals instead of reports: for every FAERS report matching search, count the values of one field, e.g. the most reported reactions for a drug (count patient.reaction.reactionmeddrapt.exact) or reports per year (count receivedate). Returns a ranked list of term and count. openFDA search syntax: field:value or field:"exact phrase", combined with AND / OR, ranges as field:[20240101 TO 20241231]. Add .exact to a text field to count whole phrases. Up to 100 terms. No match is a $0 miss (HTTP 404). Free. Data provided by the U.S. Food and Drug Administration (https://open.fda.gov). Do not rely on openFDA to make decisions about medical care; FDA does not validate these reports. FDA does not endorse looot.
