Boolean Operator Brackets are case-sensitive Boolean expression between brackets requires the Boolean terms to work properly Boolean string “(dog OR cat) AND NOT (cheese or milk)” returns results that have either of these words, but not necessarily both words appearing in the document. ( ) – brackets Boolean operators used to Boolean Search expressions together.Boolean Operator Quotations is case-sensitive (ex: Boolean string “Kerbal Space Program”). Boolean string “kerbal space program” returns documents that have this exact phrase with Boolean Operator Quotations. ” “ – Boolean operator used before a Boolean expression within double quotation marks to search for specific phrases, words, numbers, etc.Boolean Operator IMAGE returns pages that contain images and documents that do not include an image file of that specific term (ex: Boolean string “IMAGE Kerbal space program”). IMAGE – Boolean operator used before a word or phrase within inverted commas to return only results with an image extension on the website you’re searching.Boolean Operator PHRASE is case-sensitive, so upper and lowercase must match (ex: “Phrase search”). Boolean string “kerbal space program with Boolean operator PHRASE returns results with this specific phrase in any order. Boolean string “to be or not to be” with Boolean operator PHRASE returns results with these exact words in that exact order. PHRASE – Boolean operator used before a phrase or term within inverted commas to return only documents that include the specific words in the same order as they are placed with Boolean Operator Phrase.If you use NEAR between your first and last set of inverted commas then you’ll narrow down your result set to those where at least one word from the first phrase is within 10 words from the other phrase (ex: “locke NEAR kerrigan”). The Boolean search query on its own is going to return documents that have both words appearing anywhere in the document. NEAR – Boolean operator that appears between two words or phrases for determining nearness within a document.Boolean term OR NOT is Boolean operator used between two Boolean expressions to not include results of the second Boolean expression after this Boolean operator (ex: “job OR NOT interview”). Boolean string “, job, and career” documents mention either of these words. Boolean string “job OR career” returns documents that mention either word, while returning documents that mention both words if you use the Boolean term and in between inverted commas (ex: “job AND career”). OR – Boolean operator used between two Boolean expressions when you want to broaden your search query.AND NOT – Works the same way as the Boolean operator “and”, however returns search results without including pages that include the second Boolean expression after this Boolean operator (ex: job AND NOT interview).Boolean string “dog AND big” may also return similar results. Boolean string “good AND dog” will return results that contain both the words good and dog, but not necessarily in that order. Boolean expression requires the searcher (you) to work properly.
