We don't actually employ such a notion, but if I was asked to define it, 
it would be the act of using a command based on xref-matches-in-files 
(which see). The main thing that separates that from 'M-x grep', though, 
is the implementation approach.

You can use the commands based on it. And we could change the 
implementation of the aforementioned function that it would "cut" such 
long lines. In that case, the cutting could be performed using Emacs 
Lisp. 'cut' could still be used instead, though. Or 'ripgrep' could be 
instructed to do that.
