another good example is searching through paragraphs (below), which contain some combination of keywords. here the important part is ~(_*\n\n_*), or “does not contain two consecutive newlines”, in other words, the boundary of a paragraph, so it matches paragraphs! then you can combine it with any other regex to find paragraphs that contain certain keywords, but not others. this is very hard to do with traditional regexes without writing a complex and fragile pattern that tries to match the entire paragraph structure.
