Element: Integer;
The Element property determines an index of the element, which data will be placed as custom attribute values.
The dimension is set in the ISolrImportDocumentExtensionInfo.Dimension property.
Executing the example requires that the repository contains a scheduled tasks container with the TASK_CONTAINER identifier. The first task in the container is used to refresh search index. Indexing parameters for standard cube are determined in the task settings. The TAG custom field is created in indexing and repository search settings. The repository also contains a cube with the STD_ALTERNATIVE_DATA identifier, which structure corresponds to the indexed cube and also contains the ADDITIONAL_FACTORS additional dimension.

On executing the example parameters of the TAG custom field filling in will be set up in the task: values by specified element of external data source will be placed as field values. The external data source will be determined previously.
