 The Exact Term search feature that allows searching using the equals operator `=`, is disabled by default to save index space.
 It's possible to enable it for specific properties and property types using the `/alfresco/search/elasticsearch/config/exactTermSearch.properties` configuration file located in the Alfresco Repository.

 ### Mapping
 
 When you index a document that contains a new field, Search Enterprise adds the field dynamically to the document, or to the inner objects within a document. Inner objects inherit the dynamic setting from their parent object or from the mapping type. A dynamic parameter controls whether new fields are added dynamically. The default value is `true` and should be disabled to avoid a large index, unless a large index is necessary. This can be done when you create the index, using the following command:
