You can use symbols or words in your search to make your results more precise. Common search techniques include:

Plus Keywords (+)—this will search for only the specified keywords together, a + is not required but can still be used (ex: Facebook Vestager this can also be stylized as Facebook + Vestager to return the same result) 

Minus Keywords (-)—this will subtract words from your search, a - (minus) must be prefixed to the word you wish to subtract (ex: Facebook Vestager -Google this can also be stylized as Facebook + Vestager  -Google to return the same result) 

Comma separated—put a comma between keywords to widen or refine your search (ex: climate change, global warming)

Exact match—put quotes around a word or phrase to search exactly (ex: "Single European Sky")
