OpenSearch search criteria syntax

OpenSearch syntax allows you to specify how search terms are used to generate the result set.  By default, a search on a key phrase will return all pages that contain ANY words in the phrase.  For example, searching for "Grace Hopper" (without the quotes) returns all pages that contain "Grace" OR "Hopper".  The default criteria can be refined using the following syntax elements.  The syntax elements are input directly into the search text box.

+ Only returns documents containing the text after the plus sign

- Only returns documents that do NOT contain the text after the minus sign

* Only returns documents that contain the quoted text

Example 1

The following query returns all documents containing the exact quoted phrase "Grace Hopper":

"Grace Hopper"

Example 2

The following query returns all documents containing the exact phrase "Grace Hopper" and the word "bug":

"Grace Hopper" +bug

Example 3

The following query returns all documents containing the exact phrase "Grace Hopper" WITHOUT the word "bug":

"Grace Hopper" -bug
