here you can't describe the desired behavior with "|", but can with
aliases:
a.start > $date1 AND a.name like 'X%'
OR
b.start < $date2 AND b.name like 'Y%'
OR
c.start = $date3 AND c.name like 'Z%'
Wonder if that's a bad example though, as the intended result can be
obtained without splits... Need to think of a better one. Although the
idea is that there can be cases when exact control over joins is needed.
