Real-time Indexing and Effective Date

Hi Team,

In the PeopleBook "PeopleTools 8.61: Search Technology > Chapter 11 Understanding Set-Based Processing in Real-Time Indexing > Understanding Set-Based Processing in Real-Time Indexing," there is this info:

"In most of the search definitions enabled for real-time indexing, you may not need to schedule incremental indexing. However, indexes that have data with effective date changes may require the incremental indexing schedules for the actual data synchronization to take place. A change on the effective dated rows does not initiate a trigger, therefore such search definitions should be indexed using the existing indexing methods. While real-time indexing ensures data synchronization based on transaction updates, incremental indexing updates the indexed data (from prior indexing schedules) to the current date."
