FACET clause. This Sphinx specific extension enables faceted search with subtree optimization. It is capable of returning multiple result sets with a single SQL statement, without the need for complicated multi-queries. FACET clauses should be written at the very end of SELECT statements with spaces between them.
FACET {expr_list} [BY {expr_list}] [ORDER BY {expr | FACET()} {ASC | DESC}] [LIMIT [offset,] count]
SELECT * FROM test FACET brand_id FACET categories;
SELECT * FROM test FACET brand_name BY brand_id ORDER BY brand_name ASC FACET property;
