 Note that we're not going for equality alone because the chances of
-that to occur are low. So we try either '$gte' or '$lte' with equal
-probability but knowing that in some cases it may not return a result,
-even though there are documents in the result. For that reason, an
-empty result must be verified by doing a search in the opposite
+that to occur are low. So we try '$gte', and as there is a possibility
+of it may not return a result, we must do a search in the opposite
 direction.
 
 The final -- but important -- detail about this query is that both the
