Start your information-seeking by doing a keyword search in WorldCat, our library's catalog, or in our research databases (example: respiratory). To narrow your search, combine terms with "AND" (example: respiratory AND asthma). To broaden your search, combine terms with "OR" [example: respiratory AND (asthma OR allergy)].
Keyword searching - With a keyword search you look for a word, no matter where that word appears. If you like, you can specify that the word be in a particular field (e.g. the title, author, or subject), but it can be in any position (beginning, middle, or end).
When you use AND, you are specifying that both terms must be found in every item found
E.g. program* and "social isolation" and elder* and americ*
When you use OR, you are specifying that items have either of the terms, but not necessarily both. Use an OR between synonymous or similar terms for a concept.
E.g. elder* or "older adults" or aged
Some databases provide search forms (usually in an Advanced search screen) so that you don't need to type in AND or OR. For those that don't, you need to place parentheses around those terms that have OR between them.
E.g. (program* or intervention*) and ("social isolation") and (elder* or "older adults" or aged) and (americ* or "united states" or usa)
