University Libraries

The words AND/OR/NOT (sometimes called Boolean) can be used to group sets of search terms together in a meaningful way; which will improve the quality of your search results because you are customizing the results to suit your specific needs/topic.

AND

Use AND to reduce the number of items found by letting the database "know" that these two concepts (safety and water) must be together.  For example: this search on water AND safety in ArticlesPlus finds fewer items than either water or safety alone. Plus, the true context of your topic is not represented.

OR

Use OR to combine synonymous or alternate terms and increase the number of results. For example: the search water AND safety AND (Ohio OR West Virginia) in ArticlesPlus finds less items than before, but more than searching either water AND safety AND Ohio or water AND safety AND West Virginia. 

NOT

Use NOT to exclude a specific concept from your results. For example: this search on water AND safety AND (Ohio OR West Virginia) NOT lead in ArticlesPlus finds less items because it is excluding any results with the word "lead". In other words, I want materials about water safety in two states that are not about lead.

Search filters can be found in ArticlesPlus, other library databases, and even Google Scholar and are (usually) found on the left-hand side of the results page. These help to limit your results in a way you can control.

Search limiters often found:

• Date Range/Publication Date (Limit your results to a specific date range that is more relevant to the time of your topic)
• Material Type (limit to scholarly articles,news papers, etc. only- shown below)
• Subject (hone in to one specific subject scope that best represents your topic)

OHIO libraries offer a lot of ways to get full text to materials.
