db.keke.insert({name:"hky"}); db.keke.find() { "_id" : ObjectId("50222ec21905597a6291d35c"), "name" : "hky" } db.keke.find({"name":{$regex:'hk'}}); { "_id" : ObjectId("50222ec21905597a6291d35c"), "name" : "hky" } 但是 db.keke.find({name:/h

db.keke.insert({name:"hky"});

db.keke.find()
{ "_id" : ObjectId("50222ec21905597a6291d35c"), "name" : "hky" }

db.keke.find({"name":{$regex:'hk'}});

{ "_id" : ObjectId("50222ec21905597a6291d35c"), "name" : "hky" }

但是

db.keke.find({name:/hk/});

就返回空,虚拟主机,美国空间,很多资料都说可以用db.keke.find({name:/hk/});方式模糊查询啊,美国服务器,为什么我的不行?
