Hello I have the following code in my golang: 您好，我的golang中包含以下代码：

Please take a look: 请看一下：

type User struct {
    Id              int      `json:"id" bson:"_id"`
    FirstName       string   `json:"first_name" bson:"first_name"`
    LastName        string   `json:"last_name" bson:"last_name"`
    EmailId         string   `json:"email_id" bson:"email_id"`
    Password        string   `json:"password" bson:"password"`
    PhoneNumber     string   `json:"phone_number" bson:"phone_number"`
    AltPhoneNumber  string   `json:"alt_phone_number" bson:"alt_phone_number"`
    Gender          string   `json:"gender" bson:"gender"`
    Note            string   `json:"note" bson:"note"`
    Address         string   `json:"address" bson:"address"`
    AptNo           string   `json:"apt_no" bson:"apt_no"`
    City            string   `json:"city" bson:"city"`
    Zipcode         string   `json:"zipcode" bson:"zipcode"`
}

query   := bson.M{  "role"   : "customer", 
                    "status" : 1, 
                    "$or": []bson.M{ 
                        bson.M{"first_name":bson.RegEx{".*"+keyword+"*.", "i"} },
                        bson.M{"last_name": bson.RegEx{".*"+keyword+"*.", "i"} }, 
                        bson.M{"email_id": bson.RegEx{".*"+keyword, "i"} }, 
                        bson.M{"phone_number": bson.RegEx{".*"+keyword, "i"} }, 
                        bson.M{"alt_phone_number": bson.RegEx{".*"+keyword, "i"} }, 
                }}

err = c.Find(query).All(&result)

I have a record in database with first name "swati" and last name "sharma". 我在数据库中有一条记录，名字为“ swati”，姓氏为“ sharma”。 When I search "swati" then it works properly, similarly when I search "sharma" it works properly. 当我搜索“ swati”时，它可以正常工作，类似地，当我搜索“ sharma”时，它也可以正常工作。

Issue is when I search "swati sharma" then it does not return any result. 问题是当我搜索“ swati sharma”时，它不返回任何结果。 Can anybody tell how I can achieve this output? 谁能告诉我如何实现此输出？

I made the following changes in my code and it works. 我对代码进行了以下更改，并且可以正常运行。

name := strings.Replace(keyword, " ", "|", -1)
        conditions := bson.M{ "role" : config.ProviderRole, 
                                "status" : status, 
                                "$or": []bson.M{ 
                                    bson.M{"first_name":bson.RegEx{"(?i).*"+name+".*", "i"} },
                                    bson.M{"last_name": bson.RegEx{ "(?i).*"+name+".*", "i"} }, 
                                    bson.M{"email_id": bson.RegEx{".*"+keyword, "i"} }, 
                                    bson.M{"phone_number": bson.RegEx{".*"+keyword, "i"} }, 
                                    bson.M{"alt_phone_number": bson.RegEx{".*"+keyword, "i"} }, 
                                }}
    err = c.Find(query).All(&result)
