Although there is currently no hard limit for the number of search results returned, please note that the maximum value for the paginationLimitedTo parameter is 20,000. Accessing more than 20,000 hits through pagination is currently unavailable.
You can use the browse method instead to retrieve all records from an index, but please note that this method should not be used for search.
The browse method returns all results without pagination, often via iterators or similar constructs. If you require paginated results from the API, use the /browse HTTP API endpoint.
