Oracle ATG Web Commerce Search includes several sorts of auxiliary data, including type-ahead and stock availability data. By default, if you have a multi-partition index, Search suppresses errors that occur during loading for auxiliary data. If you have multiple partitions and suspect that this data is causing problems, turn on error reporting to see any issues.

To enable auxiliary data error reporting, set the enableAuxiliaryDataErrorsSuppression property of the RoutingIndexService component to false.
