Searching an exact phrase ("")
Use double quotes to tell the search engine to consider the exact words in that exact order. Be aware, however, that using an exact phrase search could limit your search and you may miss relevant results accidentally. For example, a search for [ "Dwight Eisenhower" ] (with quotes) will not result in pages that refer to Dwight D. Eisenhower.
Excluding terms (-)
Use a minus sign immediately before a word that you do not want to appear in your results. Attach the minus sign immediately before the word and precede it with a space. For example, doing a search of [ health –care ] will return results for health, but exclude references to care. In a search for [ health-care], the minus sign is interpreted as a hyphen and will not limit your search. You can exclude as many words as you wish by using the minus sign in from of all of them, for example: [ summit -g8 -iapp ].
Using the OR operator
By default, the search engine will consider all the words in a query. If you want to specifically allow either one of several words, you can enter the word OR (in ALL CAPS). For example, [ summit OR academy ] will give you results about either one of these words, whereas [ summit academy ] (without the OR) will show pages that include both those words on the same page. (The AND operator, is the default, so it is not necessary to type in the word AND.)
The order in which you enter search terms does not affect your results. You can use parentheses to adjust precedence for complex queries. For example, [ FTC OR (Data Protection Authority) ] will return any page mentioning the FTC or any pages containing the words data, protection and authority.
