It means that I can just prepend [highlight:: ... ] inline while taking regular notes, and this one page brings them all up in one place.
I do the same for other things I want to extract from across the vault (ideas, concepts, bookmarks, random-thoughts, etc). I have a folder called "Extracts" and one page each for each of these keywords.
I suppose if the outputs do get out of hand in terms of the number of results returned, I can additionally filter by file creation time and append a Vol - I, Vol - II, ... etc. to the files.
