Description
Secondary contains a secondary word or phrase in an IndexTerm. The text of a Secondary term is less significant than the Primary term, but more significant than the Tertiary term for sorting and display purposes.
In IndexTerms, you can only have one primary, secondary, and tertiary term. If you want to index multiple secondary terms for the same primary, you must repeat the primary in another IndexTerm. You cannot place several Secondarys in the same primary.
