Hi Christian, hi all
thank you for your advice. I took the approach from Christian and it’s working.
I’m using it with query-params (form-params) with RESTXQ. But it only works for
the very first fifty hits. I have no idea, how to implement the functionality
to serve the next 50 hits and so on. Is it possible to run the same query with
new $start and $max params without using the searchform again? Any further help
appreciated. Thanks in advance.
Best regards,
Günter
