If a Keyword Type does not have Case Sensitive Searching applied to it, then the value you enter on a document will not depend on the case used when indexed. For example, the Keyword Value when indexed is “John Adams”. However, when searching you may type in “JOHN ADAMS” and retrieve the document. In this instance, “John Adams” and “JOHN ADAMS” are not separate values, however, the Keyword Value will display as it was originally indexed.
See your system administrator for details on Keyword Types that may be configured for Case Sensitive Searching.
