SortContext: ISolrSortContext;
The SortContext property returns parameters of search result sorting.
It is supposed that the repository is set to work with search service based on Apache Solr. Search service base contains indexed metadata of various repository objects. Add links to the BISearch, Fore, Metabase system assemblies.

After executing the example the specified value by indexed information about dimension elements will be searched. Search results will be sorted by descending value of the name field. The results are displayed in the development environment console.
