That's how I found it, and I learned a little more about it by a need to get all mail to/from a specific client for a specific month and doing advanced searches. Granted, that's also how I learned about "site:", by going to advanced search on Google and specifying a single site to search, the resulting page shows the "site:" in the search box. > (...) but that's actually a lie, because the output if you dump that into the search field, versus if you click on a label name, don't match if you have more than about 30 messages in that label. Go try it. Good point, though as far as I can tell the number of results is the only difference... but still, it's a bit misleading.
