Background: Many of our products have a new documentation space with each quarterly or annual release. Our KC bot search uses an integration with Google search. If I set the Google search to a domain that works across all versions, the search results show very old versions of the documentation. If I set the Google search solely to a domain for the current version, sometimes Google has not yet indexed the applicable pages, in which case, we would want the previous version to come up.

I experimented a bit, and I see that if I specify two Google search domains (one for the current version and the other for the previous version), I see a mix of links between versions of the space. This might depend on whether the page has been indexed in the most recent version. However, if I specify two Google search domains, and one is for a domain that works across all versions, I only get older documentation (significantly older).

Idea: Provide a way to prioritize the search domains that are selected in a KC bot. So that the Google search will first get results from the current version, and will fall back on the other domain for the remaining links to show. This priority must be done within the KC bot, because some customers might be on an older version of the product.
