A group document is returned when the limit parameter in a request to the Match endpoint or Lookup endpoint is set to a value greater than "1" and there are more than one matches. The group document will contain a number of documents equal to the number of matches.
Documents are returned in the order they were matched with the best match listed first.
The maximum number of documents contained in a group document is 10. Sometimes the number of documents that match the input is less than the limit especially when the limit is set close to 10.
limit parameter does not impact the requirements for a record to become a match; it only allows additional matches to be returned if they exist. Each document inside the group document is counted as a transaction.
