dbForge for Mysql has the ability to run SQL scripts for Sphinx and Manticore engines. But in the comparison with your competition (EMS ...), there is no option to show FACET results. For example next script:

SELECT *
FROM company
FACET location_code
ORDER BY COUNT(*) DESC

your competition display on two tabs. Main result on first and the result of the facet on the second tab. dbForge displays just the main result. You have the ability to display more SQL queries on separate tabs, so I will be glad if you implement the same functionality for these engines.
