You can use quotes and operators (and, or) to narrow a search. You can use quotes and operators in a simple search (see Running a simple search) and in the Contains field of an advanced search (see Running an advanced search).
Use quotes and operators as follows:
Quotes
Type quotes around words to return documents that have the exact word or phrase.
For example, type "network" to find only those documents that have the word network. The search would leave out documents that have the word networking but that do not have the word network.
Or, for example, type "knowledge management" to return documents that have the exact phrase knowledge management. The search would leave out documents that have the words knowledge and management separated.
Operators (and, or)
Type and to find documents that have both words connected by the and operator.
Type or to find documents that have at least one of the words connected by the or operator.
When there are three or more values, the order of operations follows the order of definition. Each time you add an operator, the previous operators are grouped together.
