有没有办法搜索所有字段和值(除了_id)包含在给定文档字段中的文档?
示例:
{_id:..., "field1" : 2 , "field2" : 3}
{_id:..., "field1" : 2 , "field2" : 4}
{_id:..., "field1" : 2 , "field3" : 1}
要放入查询的文档:
{"field1" : 2 , "field2" : 4, "field3" : 1}
预期结果:
{_id:..., "field1" : 2 , "field2" : 4}
{_id:..., "field1" : 2 , "field3" : 1}

试试这个:
db.numbers.find({ $or: [ {"field1" : 2 , "field2" : 4}, {"field1" : 2 , "field3" : 1} ]})

我认为你需要的是:
db.yourdb.find({$and : [ {$or : [{"field1" :2}, {"field1" : {$exists : false}}]}, {$or : [{"field2" :4}, {"field2": {$exists : false}}]},{$or : [{"field3" :q}, {"field3": {$exists : false}}]}]})
