Detailed explanation-1: -Phrase searching means searching a database for words in a precise order. Different databases interpret searches differently. Some very few databases assume that two words next to each other should be searched as a phrase automatically. Most of the databases will put a boolean operator AND between two words.
Detailed explanation-2: -Use phrase searching to keep words together in a search so the database will search the phrase and not the individual words. Example: “breast cancer” will yield results that contain the exact phrase breast cancer.
Detailed explanation-3: -Phrase searching allows users to search for articles containing a phrase rather than containing a set of keywords in random order. For most databases the phrase needs to placed in double quotation marks; e.g. “skin cancer". This is particularly useful if the words on their own are common.
Detailed explanation-4: -Sometimes you may want to search for a phrase (2 or more words) in a database. When you are searching phrases, put quotation marks around the phrase. This will tell the database to search the phrase as a whole, instead of as individual words.
