This is the third part in my Google Speed-Search series. Here are the first two parts if you missed them:
Remove unwanted results with negation
This lesson introduces negation, i.e. using a minus sign (-) to specify terms you don’t want to appear in your search results. This can be useful when your results are cluttered with unrelated websites. Consider these examples:
Note: There should be a space before the minus sign, but not after.
Ice Age -movie
Despite Ice Age being a popular movie for kids, if you want information on the real ice age, you should remove the word “movie”.
Japanese cars -used
Searching for Japanese cars brings up a bunch of websites selling used cars. If you’re just interested in learning about Japanese cars, remove the word “used” from your results.
football -nfl -american
For English football, or soccer, do a search for results that don’t contain “NFL” or “American”.
"birthday cards" -free -ecard
Wrapping “birthday cards” in double quotes will make sure all the results contain exactly that phrase. Of course, if you’re looking to buy a traditional birthday card, you don’t want results containing “free” or “Ecard”.
Using negation, it’s easy to remove what you don’t want:
US President -"George Bush"
