How To Search Content Manager

Hey All! I have a client that I’m building a site for that makes very heavy use of the content manager and we need a search box on the home page that can crawl the contents of the content manager but Wix Search does not work for this. Is there any Velo resources or examples that would point me in the right direction? I did find this, but don’t see any code or any explanation of how this is done:*1w2i3ub*_ga*MjE0NDU2NjY0My4xNjc5NDMxODQ5

Are you talking about a Search-Engine, which can do filterings on a DATABASE ?
