and of course the similar aql query is very clear
select m, l, r
from m in class map,
mn in m->Map
where mn = "Chr_6",
l in mn[left]
where l > 70000,
r in mn[right]
where r < 10000
but as mentioned by fred, the version of aql in the distributed
acedb.4_7 is not yet complete so you may not yet been able to use it
