Narrow Your Search

Broaden Your Search

If you have too many results, or your results are not specific enough, then try some of these strategies to focus your search.

• Add another concept to your search (using the Boolean AND)  For example: Obesity AND Soft Drinks AND Child* instead of only Obesity AND Soft Drinks

• If you are searching with keywords, look for any relevant subject headings

• Use the most specific keywords or subject headings Example: Alzheimer Disease instead of Dementia

• Use fewer or no synonyms within a concept search (OR)

• In keyword searches, use fewer or no truncation symbols

• In subject heading searches, use subheadings to narrow the focus of a subject

• In subject heading searches, make a subject heading a "Major" subject heading

• Limit your search to type of article, language, age group, years, etc

• Field search for more precision. For example, search for words in the title field

• Look at your research question-- Is it too broad?

If you have not found any results, or very few results, use some of these strategies to broaden your search.

• Look for misspellings in your search terms

• Remove the least important concept from your search. The more concepts that you AND together, the narrower the results

• Use broader or related keywords and/or subject headings For example: Obesity instead of Morbid Obesity

• Add synonyms for each search concept (Using the Boolean OR)

• In keywords searches, use the truncation symbol to retrieve word variations

• If you have added limiters to your search, remove them

• Try a different database

• Review your research question-- Is it too narrow?
