Back at 2024 I asked it on Elastic Forums for App Search:
https://discuss.elastic.co/t/how-can-i-increase-react-app-search-ui-to-show-more-than-10-000-records-and-100-pages/353335
The answer stated it's a limitation with App Search, but now that App Search is deprecated I have switched to Elasticsearch connector and instance.
And the problem still remains, can't I increase the results to show more than 10000 records?
This really limits my SEO as google require all pages to be accessible in order to index them
