Databases might have different interfaces but they have similar functionality:
AND Use AND between search terms to narrow a search by including more than one concept, e.g. teen AND pregnancy
OR Use OR between search terms to broaden a search by including synonyms for a concept, e.g. (teen OR adolescent)
" " Use quotation marks to search for a phrase, in the exact order you type it, e.g. “health care reform”.
* Use an asterisk to search for multiple versions of a word, e.g. obes* will allow you to search for obesity and obese.
() Use parentheses when you are using synonyms (see OR above).
