Reverse AutoFill Keyword Set Lookups allow you to use Secondary Keyword Values to search for an AutoFill Keyword Set during indexing or re-indexing so that the AutoFill Keyword Set can be used to index or re-index the document.
Reverse AutoFill Keyword Set Lookups work correctly with encrypted Keyword Types as long as the entire secondary value is searched. Partial terms and terms with wildcards cannot be used to search from secondary values with encrypted Keyword Types.
