Please add a section describing how to $pull subdocuments from an array, since $elemMatch doesn't work and instead, we need to use (what I think is) a non-standard query operation.
For example, if you have this document:
{x: 0, y: [ {a:1} , {a:2} ]}
this works:
{$pull: {y: {a: 2}}}
but this does not:
{$pull: {y: {$elemMatch: {a: 2}}}}
