Search install scripts by features used?

I am looking for a way to search/grep/scrape install scripts from lutris, to find ones that use certain features from the yaml schema.

This came up while trying to figure out how write an install script, (more specifically how to use extract with multi part/slice files.)

Is anybody aware of a method to filter games on lutris not by game features, but by whether the handcrafted install script contains certain words?
