Databases use the words AND, OR, and NOT as search commands to perform certain actions.
You can use these search commands within the same search box to link concepts or between search boxes to separate concepts.
In the example below, OR is used to connect alternate terms for the same concept. AND is used between search boxes to link the concepts.
Use "quotation marks" ("inverted commas") to search for a phrase.
For example, if you want to find articles that mention physical activity, try searching for “physical activity”. Doing this means that the database will only show you results where the words in the phrase are together in that exact order. This helps eliminate irrelevant results.
Watch the video below for a demonstration of how to search using AND, OR and phrase searching.
When you type your keywords into the library's search bar, it will automatically look for the words anywhere within the results.
You can use field searching to tell the database where to look for your keywords, so that you only get results where your keywords are mentioned in places like an article's abstract or title. This can help you narrow your search to articles that are more focused on particular aspects of your topic.
To do this, click on the "Select a Field" drop-down menu next to each search bar.
Watch the video below to learn more and to also learn how to use filters in your search.
