Boolean Searching (AND, OR, NOT)

Boolean searching allows you to combine search terms using the three Boolean operators AND, OR, NOT. To execute a Boolean search, enter the required terms separated by the Boolean operators you wish to use.

Note: When you transfer more than one search term from a browse index to a search box, the software automatically combines them using the Boolean operator OR.

AND

The AND operator retrieves all records that contain both of the terms entered. This normally retrieves fewer records than searching one of the terms on its own.

For example:

OR

NOT

The NOT operator retrieves all records that contain the first term entered but not the second.
