使用数组进行mongodb查询

Question

我有这个系列：

{"_id"=>BSON::ObjectId('5728cd81c08460ead'), "age"=>4, "name"=>"Diogo"}
{"_id"=>BSON::ObjectId('5728cd81c08460ead'), "age"=>22, "name"=>"Tiago"}
{"_id"=>BSON::ObjectId('5728cd81c08460ead'), "age"=>15, "name"=>"Marie"}
{"_id"=>BSON::ObjectId('5728cd81c08460ead'), "age"=>2, "name"=>"JJ"}
{"_id"=>BSON::ObjectId('5728cd81c08460ead'), "age"=>44, "name"=>"John"}

和这个名字数组：

names_array = ["John", "Marie", "Tiago"]

如何使用names_array在mongodb集合中搜索名称？

我想要这个输出：

{"_id"=>BSON::ObjectId('5728cd81c08460ead'), "age"=>4, "name"=>"Diogo"}
{"_id"=>BSON::ObjectId('5728cd81c08460ead'), "age"=>22, "name"=>"Tiago"}
{"_id"=>BSON::ObjectId('5728cd81c08460ead'), "age"=>15, "name"=>"Marie"}

此查询不起作用：

coll.find( { name: names_array } )
