It is recommended that you work with a librarian to help you design comprehensive search strategies across a variety of databases. Writing a successful search strategy takes an intimate knowledge of bibliographic databases.
Using Boolean logic is an important component of writing a search strategy:
"AND" narrows the search, e.g. children AND exercise
"OR" broadens the search, e.g. (children OR adolescents) AND (exercise OR diet)
"NOT" excludes terms, e.g. exercise NOT diet
"*" at the root of a word finds all forms of that word, e.g. (child* OR adolescen*) AND (exercise* OR diet*)
parentheses ensure all terms will be searched together as a set
quotations around a phrase searches that exact phrase, e.g. (child* OR adolescen* OR "young adult*")
