i have a datbase of about 1.5 million log entries that i want to search based on 
subject (not indexed because it's seldom used).  when i try, i get a fatal warning 
that i cant seem to kick.  i have rtfm, and changed max_join_size=2000000 in my.cnf to 
hopefully make it run without the fatal warning... that didnt work.

if i set sql_big_selects=1 and run the query, it takes 10 minutes to return any data.

mysql> SELECT * FROM email WHERE 1 AND subject = 'RE: TEST EMAIL' ORDER BY `id` DESC 
LIMIT 0,25;
ERROR 1104: The SELECT would examine too many records and probably take a very long 
time. Check your WHERE and use SET OPTION SQL_BIG_SELECTS=1 if the SELECT is ok

can someone offer some advice to help make this query work.  btw, the order by `id` is 
the primary key.

thanks,
dallas
