Can I actually use sphinxQL with SphinxSE plugin? Like this:
SELECT * FROM t1 WHERE query='SELECT id FROM products GROUP BY region, price';
Nope. Two completely different ways of accessing sphinx.
SphinxSE under the hood uses the SphinxAPI.
SELECT * FROM t1 WHERE query=';select=id;index=products;groupby=attr:region,price';
Although I dont know if the multiple attribute group by will work.
