Search results include
Enumerable so you can iterate over them using
each or any method defined in Enumerable.
To optimize the processing of large searches, data is retrieved from the server lazily.
Initially, the server returns a list of ids that matched the search criteria. While you're iterating over search results, the data for each record is fetched dynamically. This causes race conditions to exist when records are modified on the server while you are iterating over them.
If a record is deleted server-side while you are iterating over the results, that record is skipped.
If a record is updated server-side while you are iterating over the results, one of two things could happen:
- the record still matches the search criteria and the modified record is returned
- the record no longer matches the search criteria and is skipped
Because of the race conditions described above, you can't know how many search results you have while iterating over them. You do, however, know the maximum number of results that will be given.
search_results = gateway.transaction.search do |search| search.amount <= "20.00" end search_results.maximum_size #=> 33
Transaction searches return a maximum of 50,000 results; all other searches return a maximum of 10,000 results.
