## Brief description of issue
A query to api with *search_parameters[limit]* greater than *21* returns an incorrect number of images.
*search_parameters[limit]=21* returns 25 rows
*search_parameters[limit]=27* returns 31 rows

Reproduce the API request in the issue with search_parameters[limit] set to 21 and 27, then compare the returned row counts. Review the documentation for search_parameters[limit] and search_parameters[offset] to determine the expected behavior; done means the discrepancy and correct behavior are reflected in the API documentation.
