Question

我有一个mongoDB查询

    (ronin) pratyusha@pratyusha-Q304UAK:~/Projects/ronin$ python Retrieval-Eval.py
No handlers could be found for logger "gensim.models.doc2vec"
<IPython.core.display.HTML object>
Can you suggest a spa for us?
Are transport facilities available here?
Traceback (most recent call last):

如何用数组替换表达式test.find({$or : [ {"timeIn":"2018-1-31 11:57"},{"timeIn":"2018-1-31 11:58"},{"timeIn":"2018-1-31 11:59"} ] }, {"email": 1, "_id": 0}).toArray(function (err,data){ if (err) throw err; console.log(data); });。喜欢这个

{"timeIn":"2018-1-31 11:57"},{"timeIn":"2018-1-31 11:58"},{"timeIn":"2018-1-31 11:59"}

Answer 1

尝试$in，需要匹配一组值

test.find({timeIn : {$in: ["2018-1-31 11:57","2018-1-31 11:58","2018-1-31 11:59"]}  }, {"email": 1, "_id": 0}).toArray(function (err,data){
  if (err) throw err;
  console.log(data);
});

Answer 2

亚历克斯，你想要这样的东西：

var arrQuery = [];

var query1 = {'name':'AC3 Series Charger'};
var query2 =  {'price':200};
var query3 =  {'type':'tv'};
arrQuery.push(query1);
arrQuery.push(query2);
arrQuery.push(query3);

db.products.find({$or:arrQuery})

只需根据您的需要进行调整。
