Refine By

Additional Keywords allows you to refine your results by specifying keywords within selected fields. Available fields are displayed in the drop-down menu. [Note that results are ranked by relevancy when searching the Title, Abstract, Subject Terms, Full-Text, and All fields.]

  • Use quotes to search for exact phrases (e.g., "space shuttle") or use the Advanced Search and select "Exact Phrase" from the first drop-down menu.
  • Use an asterisk ( * ) as a wild card to expand term searching (e.g., comput* searches for computation, computational, computer, computers, computerization, etc.).
  • Retain hyphens in words that commonly use them (e.g., x-ray).
  • Search for author in several ways (e.g., "Armstrong, Neil" or "Armstrong, N.").
  • Find multiple authors in one search by using last names only (e.g., Armstrong Aldrin).
