Docs search does not work for the "@>" operator

Hello Postgres Docs,

When searching on the Postgres docs website, searching with the strings
`@>` or `"@>"` returns no results.

Ordinarily, I would expect to see results returned including this page (which
was the page I was looking for):
https://www.postgresql.org/docs/17/functions-range.html

Can the search be updated to work with these characters please?

Thanks,

Jai
