`prev_page` field is always `null` on search
Current Behavior
prev_page is always null.
Expected Behavior
It should return the seek for the previous page if there is one.
Steps To Reproduce
You can see the issue on docs.rs:
Go to https://docs.rs/releases/search?query=sysinfo Click "next page"
Then you can see that there is no "previous page" button. I originally suspected a bug on docs.rs side but after investigating, it looks like the ["api", "v1", "crates"] query always return a null prev_page in the JSON response.
Environment
No response
Anything else?

That's intended behavior. The way seek pagination is implemented we can't offer reverse traversal without sacrificing performance.
I see. I suppose we can store the previous page in the cookie session... Gonna find something out.

I don't expect significant performance issues. It would only involve some reverse handling (including query and result processing). This is actually one of the enhancement items on my backlog.
