I want something with example URL and what is shows in response result. Using the field faceting, we can retrieve the counts for all terms, or just the top terms in any given field. The trade-off, is that the proximity query is slower to perform and requires more CPU. Throws SolrServerException if the Solr Server had failed to satisfy the query.
