Thanks for the quick responses!
Yeah, I’m really looking to get ALL results at the reply-level, like most forums are able to do. Here’s a screenshot of one such forum, where it returns all replies that contain “zotero”.
I suppose a related discussion is why Discourse has chosen to just return one result per topic? Is the idea to reduce clutter as much as possible? And, if so, is it considered that one result per matched topic is sufficient - people can then do a search/browse within any specific topic?
