Searching by keyword in Search@UW can be challenging. To be successful, break your topic down into its most basic concept(s). Here are examples of two similar searches on a single topic that provide complimentary search results.
1). Search on the term "ethics" and your basic topic -- e.g. ethics AND assisted suicide
2). Narrow your search down by using relevant subject term(s) while expanding your concept terms using Boolean operators and/or/not -- e.g. "moral and ethical aspects" AND (assisted suicide or euthanasia)
