About this search
If you search for an exact phrase, the search engine will only report items that contain that phrase in the title, abstract, or graduation standards fields. This is the equivalent of a Boolean AND search.
If you search for all words, the search engine will report items that contain any of the words you list in the title, abstract, or graduation standards fields. This is like the Boolean OR search.
For example, searching for the phrase 'environmental protection' will find a small set of records that contain that exact phrase. Searching for all words will result in a large number of records that have either word in the title, abstract, or grad standards fields.
