Excluding a specific page from Congo's search

[CaptainStormfield]

I am a Congo (and a Hugo) newbie, and loving it so far. What is the recommended way to exclude a single page from Congo's search?

(Apologies if this has been asked before. I searched discussions but didn't see anything relevant.)

I similarly would like the option to specify, in config params, particular sections to exclude from the search index
