Query Execution
It will be nice to have support $elemMatch projection on nested documents.
For example when schama look like this to support multilingual:
{
"name": [
{
"locale": "en",
"value": "milk"
},
{
"locale": "de",
"value": "milch"
}
],
"brand": {
"attribute": "value1",
"name": [
{
"locale": "en",
"value": "MilkBrand"
},
{
"locale": "de",
"value": "MilchMarke"
}
]
}
}
this query is unsupported
db.test.find({},{name:{$elemMatch:{locale:"en"}},"brand.name":{$elemMatch:{locale:"en"}}})
