Choosing URL structure (technical SEO)

Hi, I'm pretty new to SEO, just a few months old.

I'm building a website and I'd like to know some expert's opinions about this issue:

I've built a search system for my site, which generates tailored searches for people. Those searches can later be shared in social media, e-mails, ...

I have 2 URL formats to choose from:

domain / search page ? id = <long id>
domain / search page / <long id>

(or in other worst, treating the search results as a single page, or treating every search result as a different page)

The idea is to use those search pages as a way to build links, but I don't know if it'd be better, SEO wise, to have a single page with lots of links pointing to them, or have lots of pages with few links. At the end, the amount of links will be the same, just the distribution will be different.

Also, domain / search page (without id) will probably redirect you to the search start page.

Thanks in advance!

I am trying to understand but I don't fully get what you are trying to do.

Just a suggestion but why not create a fake url so we can better understand what you're asking?

Thanks for the answers, sorry for the confusion. In example

https://www.mydomain.com/searchResults?id=48ac89d8g985
or

https://www.mydomain.com/searchResults/48ac89d8g985

The idea is that on the eyes of Google (AFAIK), the first one is the same page with a parameter, while the second one is a different page for each id.
