Use the DQM Index Optimization program to optimize interMedia indexes. You can schedule this program to run on a periodic basis. In general, you can run the DQM Index Optimization program less frequently than the DQM Synchronization program. The DQM Index Optimization program improves the performance of interMedia searches, which gradually degrades over time. You should run this program once in a while, but frequent optimization is not mandatory.

The DQM Synchronization program, however, synchronizes data between the TCA Registry and the staged schema, so you should run this program as often as possible to keep the search results accurate. See: DQM Synchronization Program.

Prerequisites

Before you submit the DQM Index Optimization program, you must make sure that both the staged schema and interMedia indexes exist.
