A collective term that refers to the many types of indices in the MDEX Engine. For example, in the standard search index, each entry corresponds to a searchable document containing the correct term; in the wildcard search index, each entry corresponds to a document enabled for wildcard search that contains the correct term. Other indices are also used.
An empty MDEX Engine index is created when you install the MDEX Engine, run the mkmdex command, and start the MDEX Engine. When you make a change to your data records or configuration, depending on the change, this causes the index to be updated, either through an incremental index update, a configuration update, or a full index refresh.
