A collection with PERIODIC indexing mode is indexed only when FTR indexes the collection. When a row in a collection with IMMEDIATE index mode is added, updated, or deleted, the row is indexed immediately. The new or updated row is immediately available for FTR searches. By default, all FTR collections are created using IMMEDIATE indexing.
You can set the indexing mode of a collection through the FTR Server Configuration command in the SmartPlant Foundation Desktop Client. For more information, see Configuring FTR Server.
