For the following keyword search,
below on the left is the database's controlled vocabulary and limits, where you can narrow your results, or use the terms to start a new search.
Not sure how to begin searching your topic (what terms to use)?
Enter some words in the search boxes and then use the way the database categorizes the results--and the results themselves--to give yourself ideas: expanding, narrowing, or reformulating your search terms.
Then, use the limits and controlled vocabulary (subject terms or descriptors) the database provides. Depending on the database, these might be displayed in a sidebar on the left or right of the list of results.
Narrow your current search or start a new search using the subject terms. Doing so will help increase the relevancy of the articles retrieved. (See illustration in the box to the left.)
When you click on a particular record, the controlled vocabulary will be included in the full citation. There may also be an abstract, or summary, that is another potential source of keywords or concepts for you to search.
