Not a very major update, but I figured it was worth letting everyone know: search has been expanded a bit to also cover topics' tags in addition to their title and markdown (for text topics). So if you search for a term that was only included in a topic's tags but not its title/text, it should come up in the results now.
On that subject, are there any other pieces of data that you think should be included by default in search? In the future, I'd like to support searching certain parts of data deliberately (for example, maybe by writing a query like
url:article to find only link topics with "article" in their url), but that's different from including it automatically in all searches. As a specific example, if you search for "youtube.com" or even "youtube", should all link topics from YouTube come up, or only topics that have the word "youtube" somewhere in their title/text/tags?
