What a strange question. Usually, I want my search results be deterministic,
not random ;-)

Anyway. Catalog searches return sequences.

The "random" (maybe "whrandom") module contains a "choice" function
that allows you to randomly select an element from a sequence.
Both modules are directly available to both Python Scripts and ZPT.

Combine the above and you get a randomly selected catalog hit.

When you want more than one, repeat it in a script and append the
results.
