Use the features found in the database to narrow or focus your results. Add a date range or select a specific subject area identified by the database.
When using Nexis, be sure to select cases and then federal cases before entering your search terms!
It is usually a good idea to start out broadly, so using just one or two of your topic terms is a good way to begin. Once you have a set of results, you can begin narrowing down your results by entering one or more terms. Searching in a specific field such as "Subject" or "Title" will narrow or focus your results.
