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.
