In this example, the Document Update Processor re-indexes the document to replace the existing Chart value with the value provided in the HL7 message. Because Chart is the primary Keyword Type in an AutoFill Keyword Set, the new value triggers updates to the secondary Keyword Types.
In this case, the HL7 message does not provide any values for the secondary Keyword Types. If the HL7 message did provide conflicting values for the secondary Keyword Types, the HL7 values would override the secondary values populated by the AutoFill Keyword Set.
