I would like the KC bot search to include results both from our documentation site (found via Google search) and from our YouTube channels.  For a Google search to find content from our channels, we must specify the YouTube channel as a parameter before the search term, as in:

site:https://youtube.com @BMCdocs/videos aiops

However, when configuring Google search domains, I cannot include a space. If you could include an optional parameter, that would be great. I expect that there are other use cases for an additional parameter.
