Changing URL structure

Hi,

I’m working on an art project where I need to be able to query search terms on different categories.

I’m looking to do something like this:

website.com/{category}/{search-term}/ – gives me search results

and also

website.com/{category}/{number}/ – gives me second page of category

I’ve been looking through loads of sites as well as this and I can’t find any information!

Any help would be great!

Thanks,
Hal
