- Information Management Platform version 6.4 or higher.
- Indexes were migrated after an Information Management Platform upgrade from version 6.2 (SP0) or earlier.
The 'IndexEngine' value in at least one of the indexes' settings.txt file is not specified. The indexes where 'IndexEngine=1' is missing are likely coming from a past migration from Information Management Platform version 6.2 (SP0) or lower.
As these old indexes were created with Information Management Platform version 6.2 (SP0) or earlier, all these indexes use the HAPI engine.
Add 'IndexEngine=1' to the "ZyLAB Data\Indexes\<INDEX_NAME>\SETTINGS.TXT" file of the HAPI indexes that don't have it.
This line should be added within the '[ZyBuild]' section of the settings.txt file.
For instance, the file should look like this.
