Limits results to articles with full text.

Limits search results to articles from peer-reviewed journals.

Using the published date option, you can limit your results to a certain time period – for example, anything published within the last 5 years.

There aren't a lot of foreign-language articles in the databases, but there are enough that it can be frustrating if you keep getting articles in Turkish or Serbian. Some articles might have an abstract in English, but the rest of the article is in a foreign language. Check the English Language checkbox to make sure all your results are in English. 

Many health databases feature built-in search filters, which can be used to limit search results by age group

If you use the filter rather than a keyword, you can guarantee that the resources returned are relevant to your topic. 

Keywords search everywhere for the term, including full text (unless otherwise specified). The keyword may only appear once in the text of a paper rather than being a substantial aspect of the article. Whereas when you choose a specific category under a filter, that category will be a substantial aspect of the article.

For example, in CINAHL:  

• The search sleep AND teenager will yield many results, but in some resources, "teenagers" might not be the focus of the study or research. Additionally, researchers may use other synonyms, such as adolescence or youth, and the database would not include these resources in the search results. 
• On the other hand, if you search for just the word sleep, then add the filter "adolescent: 13-18 years", all your search results will be specifically about people aged 13-18 and sleep. 
• Addtioanlly, the second search results returns significally more search resutls 

Many health databases feature built-in search filters, which can be used to limit search results by sex. However, it should be noted this is generally only true for males and females. If you are interested in researching transgender people, it is better to use a keyword rather than a filter.

For example, in CINAHL:  

• The search cancer AND women will yield many results, but in some resources, the focus of the study might not be about women and cancer. 
• On the other hand, if you search for just the word cancer, then add the filter "females" all your search results will be specifically about women and cancer. 
• Additionally, the second search results returns significally more search resutls
