No, the maximum value for the paginationLimitedTo parameter is 20,000.
We recommend optimizing the relevance of search results returned on the first page rather than focusing on displaying more than 20K hits in the first page of search results.
Although you can use the browse method to retrieve all records from an index, we do not recommend using this method for search. Please note that 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.
