Advanced Search allows you to more specifically use search terms and Boolean operators.

The search filters provided are Title, Author/Creator, Subject, ISBN, ISSN, and User tags. You can enter some or all of these search filters to narrow your results. Using the Boolean operators AND, OR, or NOT can also help to make your search more specific. AND will make sure to only show you results that use both the above and below search term. OR will show you results that feature the above or the below search term. NOT will show you results that use the above search term but not the below search term. You can also change "contains" to "contains exact phrase," "starts with," or "equals exact phrase."
You can change the Resource Type to Journals, Books, Articles, Images, Sound recordings, Video/Film, Dissertations, or Scores. You can change the language to only show you results in Arabic, Chinese, Czech, Danish, Dutch, English, French, German, Modern Greek, Hebrew, Italian, Japanese, Korean, Latin, Norwegian, Portuguese, Russian, Spanish, Swedish, or Turkish. You can change the start and/or end dates of when the search results were published to help ensure you only get recent results or only results from specific eras.
