The only advice I can give you at this point is to provide both the
EXPLAIN output and the query itself in formats more easily readable for
those that could help you. This EXPLAIN you post below is totally
whitespace-mangled, making it much harder to read than it should be; and
the query you posted, AFAICS, is a continuous stream of lowercase
letters. The EXPLAIN would be much better if you posted it as an
attachment; and the query would be much better if you separated the
logically distinct clauses in different lines, with clean indentation,
using uppercase for the SQL keywords (SELECT, FROM, WHERE, etc). That
way you're more likely to get useful responses.
