FilterContext: ISolrFilterContext;
The FilterContext property returns filtering parameters of search results.
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. The search is executed taking into account the specified filtering parameters by the "name" field values. The results are displayed in the development environment console.
