In order to run an advanced search, click the Advanced Search option under the Search button. The advanced search options will appear:
Each row in the advanced search consists of following elements:
- The middle element is the text box, into which you should enter the word or words you wish to use in your search.
- On the left is a drop-down menu that contains a list of fields:
- Below this is a drop-down menu that lists common Boolean relationships between search terms:
AND indicates that the search term(s) in the following row must appear in addition to the one(s) in the current row.
OR indicates that the search term(s) in the following row can replace those appearing in the current row.
NOT indicates that the search term(s) in the following row must not appear in the search result.
- The last row, since it does not have a row following it, does not have a drop-down menu; instead it contains a + symbol that can be clicked to add an additional row. When there are more than two rows, all rows but the last offer an X symbol that, when clicked, deletes that row.
The above search terms will search for articles on the subject of “Endangered species” that refer to either orangutans or tigers, so long as their author is named Smith.
- Finally, there is a drop-down menu that allows you to limit your results to a given date range:
If you select Custom, four additional drop-down menus appear, allowing you to specify starting and ending dates by month and year:
When you have completed entering your search criteria, you can click on the new Search button that appears at the bottom of the advanced search window. If you wish to return to the simple search, click the – button in the upper right (which appeared in place of the + button you used to open the advanced search window).
