AND and OR connectors

The AND and OR connectors connect two expressions.

If you use the AND connector, both expressions (before and after the AND) must be found in a document.

If you use the OR connector, either of the expressions must be found in a document.

For example:

If you type apple pie AND poached pear, the search returns any documents that contain both phrases.

If you type apple pie OR poached pear, the search returns any documents that contain “apple pie,” “poached pear,” or both.

If you intend to use more than one connector, use parentheses to indicate precisely what to search for. For example, without parentheses the search query apple AND pear OR orange has two possible meanings: (apple AND pear) OR orange or apple AND (pear OR orange).
