-- Returns a list of findings that match the specified criteria.
--
-- If finding aggregation is enabled, then when you call @GetFindings@ from
-- the aggregation Region, the results include all of the matching findings
-- from both the aggregation Region and the linked Regions.
--
-- This operation returns paginated results.
