Knowing how to do what you did is vital for using a search engine effectively. It's not possible for a search engine to know what you want when a word has multiple meanings (well, not yet, anyway). It could have just as easily have been the other way around, where OP wanted to search for a niche band but all they could find is astronomy things.

Adding context like "band", "astronomy", etc is important if you're googling anything non trivial. Sometimes you even need to identify different words to search. Eg, there's a programming language called Go. But "go" is such a generic word that it's hard to search for. Searching for "golang" tends to help a lot.
