OYSTER / 7-OYSTER_User_Defined_Inverted_Index

A new feature has been added to OYSTER Version 3.3 that allows the user to define an inverted, match-key index. The User-Defined Index (UDI) feature can significantly reduce run-time. However, a poorly designed UDI can significantly increase false negative error rates. This section defines the concepts involved for UDI and details the efforts what must be used to properly align the UDI with the defined match rules.
