Query 10 (02/22/16)
I have a collection with a simple array of values and also with a nested collection. If I do a negative look-ahead $regex search on the documents with everything works fine but if I do the same search on documents with a nested collection it doesn't work. For example:
sample list collection
{
"_id": ObjectId("54deb2ed4e5018cf1c737b8d"),
"values": [ "apples", "peaches", "bananas" ]
}
{
"_id": ObjectId("54df5b40f546cf4c25013190"),
"values": ["grapes", "oranges" ]
}
db.sampleList.count( { 'values':{$regex:"^(?<!appl).*", $options:'i '} }); // 1
sample nested collection
{
"_id": ObjectId("54e28b6caaadddb844d1f40a"),
"values": [
{
"value": " apple",
"label": "Choice 1"
},
{
"value": "peach",
"label": "Choice 2"
},
{
"value": "banana",
"label": "Choice 3"
},
{
"value": "orange",
"label": "Choice 4"
}
]
}
{
"_id": ObjectId("54eb580ee163c16b23145536"),
"values": [
{
"value": "orange",
"label": "Choice 1"
},
{
"value": "banana",
"label": "Choice 2"
},
{
"value": "peaches",
"label": "Choice 3"
},
{
"value": "grapes",
"label": "Choice 4"
}
]
db.sampleList.count( { 'values.value':{$regex:"^(?<!appl).*", $options:'i '} }); // 2
