About Boolean Searches

Boolean searching allows you to use the AND, OR and NOT search operators. On the Ohlone College website, boolean searches can be performed from the Search page and from the search results page.

1. Choose "Boolean" from the Match dropdown menu
   

2. Then, enter your search terms using AND, OR, and/or NOT search operators - see the examples.

Return to the Search page.

Notes:

1. The ht::/Digg search engine used on the Ohlone College server does not, at this time, support phrase searching (consecutive words specified by using quotation marks around the words - i.e., "garrett yee"). However, you could do a boolean search for garrett AND yee which would match pages containing both garrett and yee but not necessarily garrett immediately followed by yee.
2. Phrase searching is supported by the Google search option on the Search page - i.e., you can search for "garrett yee" (include the quotes in phrase searches). Learn more about Google's advanced search options.
