Five Google Search Features You Haven’t Been Using

Are any of these new to us, or are we all expert-level googlers now? Someone did a list of google search features you might not know about. Do you use any of these, and are they helpful?
1. Hyphen searches. If you put a hyphen in front of a word, it excludes results with that word. The example Google gives is “jaguar speed -car”. So, how fast the animal is, not the car.
2. Tildes. This thing: ~. If you put one in front of a word, it also searches for synonyms of that word. So something like “music ~classes” will also look for music “lessons” and music “coaching.”
3. Searching specific sites. Start with the word “site”, then a colon, and the URL for the site you want to search. For example, “site:olympics.com figure skating”
4. Searching for different file types. There’s a dedicated “image search” button, but you can also specifically search for things like PDFs and MP3s. Just start your search with “filetype”, followed by a colon. Example: “filetype:PDF”
5. Asterisks. If you don’t know a word, put an asterisk in there. It’s useful if you don’t know the name of a song but know SOME of the lyrics. For example, “falling down like * into *” is vague. But Google knows you probably mean “like pieces into place” from the Taylor Swift song “All Too Well”.
