Не могу правильно вывести аналоги в TecDoc

Использую на сайте базу TecDoc. Пытаюсь вывести аналоги запчастей

SELECT DISTINCT
IF (ART_LOOKUP2.ARL_KIND = 3, BRANDS2.BRA_BRAND, SUPPLIERS2.SUP_BRAND) AS BRAND,
IF (ART_LOOKUP2.ARL_KIND IN (2, 3), ART_LOOKUP2.ARL_DISPLAY_NR, ARTICLES2.ART_ARTICLE_NR) AS NUMBER,
ART_LOOKUP2.ARL_KIND
FROM          ART_LOOKUP
LEFT JOIN BRANDS ON BRANDS.BRA_ID = ART_LOOKUP.ARL_BRA_ID
INNER JOIN ARTICLES ON ARTICLES.ART_ID = ART_LOOKUP.ARL_ART_ID
INNER JOIN SUPPLIERS ON SUPPLIERS.SUP_ID = ARTICLES.ART_SUP_ID
INNER JOIN ART_LOOKUP AS ART_LOOKUP2 ON ART_LOOKUP2.ARL_ART_ID = ART_LOOKUP.ARL_ART_ID
LEFT JOIN BRANDS AS BRANDS2 ON BRANDS2.BRA_ID = ART_LOOKUP2.ARL_BRA_ID
INNER JOIN ARTICLES AS ARTICLES2 ON ARTICLES2.ART_ID = ART_LOOKUP2.ARL_ART_ID
INNER JOIN SUPPLIERS AS SUPPLIERS2  ON SUPPLIERS2.SUP_ID = ARTICLES2.ART_SUP_ID
WHERE
ART_LOOKUP.ARL_SEARCH_NUMBER = '1244211212' AND
(ART_LOOKUP.ARL_KIND IN (3, 4) AND BRANDS.BRA_BRAND = 'MERCEDES-BENZ' OR  SUPPLIERS.SUP_BRAND = 'MERCEDES-BENZ') AND
(ART_LOOKUP.ARL_KIND, ART_LOOKUP2.ARL_KIND) IN  ((1, 1), (1, 2), (1, 3),(2, 1), (2, 2), (2, 3),(3, 1), (3, 2), (3, 3), (4, 1))
ORDER BY BRAND, NUMBER;

По идее, оно должно вывести только те запчасти, в которых произволитель MERCEDES-BENZ, но оно выводит и другие. Что я написал не так?
