AND Used to retrieve a set in which each citation contains all search terms Example: boat AND sail AND is the default operator used in PubMed. If you don’t include operators in your search, PubMed will automatically use AND between terms The retrieval is only the overlap of the results for each term –those record in which both terms appear. boat sail NOT Retrieves a set from which citations to articles containing specified search terms following the NOT operator are eliminated. Example: boat NOT sail ???????????????????????????
