How important is the order of columns in indexes?

...tioned in one Answer. So, what order should be used? Start with column(s) tested with =, in any order. Then tack on one range column. For example, the very-low selectivity column must come first in this: WHERE deleted = 0 AND the_datetime > NOW() - INTERVAL 7 DAY INDEX(deleted, the_datetime) ...

That's many hours of time wasted that could be better spent doing anything else. "But I...
