How to create a web crawler filling and submitting every search bar using Jsoup?

Is it possible to write web crawler in Jsoup such that will submit every kind of search bar on every website?

For exampe, here we have list of websites:

https://www.amazon.com/

http://ift.tt/11kthVY

https://www.ebay.com/

https://www.lidl.com/

https://www.tesco.com/

http://ift.tt/2z56ofY

(and infinite number of websites with search bar here.)

At every of listed above website you will find search bar but every of them is different. Is it possible to write a web crawler using Jsoup that will fill a search field with given phrase and will return to me a website with results?

I am going to use that crawler in android app so I choose Jsoup. If there is any other web crawler library that is supported on Android I can choose also another one.

Thx in advance! :)
