Access website and its functionality using java (jsoup)

I was wondering if there is a library for java where it is possible to search on a website. I would like to use the functionality of the website and read out the results using 'JSoup'.

I can use the search engine using placeholders

Example: searchSite On the left of the side is a tool where I can refine the search (contacts, voltage,...). These elements I want to manipulate.

It would also be preferable to run this in the background (firefox or chrome) over this Web-Java-Interface

I looked at a commercial tool like 'Parsehub' or the 'jdmp' package for java.
