go - Search based on regular expression in mgo does not give required result -


hello have following code in golang:

please take look:

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 record in database first name "swati" , last name "sharma". when search "swati" works properly, when search "sharma" works properly.

issue when search "swati sharma" not return result. can tell how can achieve output?

i made following changes in code , works.

      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)
