MongoDB .find with multiple $or statements, syntax error 'unexpected token ]'? - mongodb

Question

A user may send or receive a message, and should be able to archive his/her message regardless.
This .find should therefore return any docs where userA is in to.username or from.username, with view.archive:true. From there, the second $or should filter the results from the first $or to only include the matching docs where the message's value.1:true, value.2:true, or value.3:true
Right now, however, there is SyntaxError: Unexpected token ] for the closing ] on the first $or
Models.Messages.find(
{
"$or" : [
{
"to": {
"$elemMatch": {
"username": 'userA',
"view.archive": true,
"view.bin": true
}
}
},
{
"from" : {
"$elemMatch" : {
"username" : 'userA',
"view.archive": true,
"view.bin": true
}
}
}
],
"$or": [
{ 'value.1': true },
{ 'value.2': true },
{ 'value.3': true },
{ 'value.4': false }
]
}
).sort([['updated','descending']]).exec(function (err, messages) {
Both of these messages should be found for userA:

Thanks to #JohnnyHK for his answer to this question as it also applies here.
Was under the impression that $and was implied with .find in MongoDB, but when combining $or filters it appears to be necessary, as also pointed out by #soulcheck.
Models.Messages.find(
{
$and: [{
"$or" : [
{
"to": {
"$elemMatch": {
"username": 'userA',
"view.archive": true,
"view.bin": false
}
}
},
{
"from" : {
"$elemMatch" : {
"username" : 'userA',
"view.archive": true,
"view.bin": false
}
}
}
]}, {
"$or": [
{ 'value.1': true },
{ 'value.2': true },
{ 'value.3': true },
{ 'value.4': false }
]
}
]
}
).sort([['updated','descending']]).exec(function (err, messages) {
