I can use my query to filter/search for a specific user and I'm happy with that. However, It doesn't return the correct or full amount of data that I'm expecting, as shown below. I need the bio and other fields of data to be included. Even as I tried the answer down below I'm still returning the wrong data. It must be how I'm appending the data?

type Profile struct {
    Username string

    Verified  bool
    Protected bool

    Avatar string
    Banner string

    FollowerCount  int32
    FollowingCount int32
    TreatCount     int32
    LikeCount      int32

    Name     string
    Bio      string
    Website  string
    Location string
}

func SearchProfiles(filter string) ([]models.Profile, error) {
    results := []models.Profile{}

    filterr := bson.D{{Key: "username", Value: primitive.Regex{Pattern: filter, Options: ""}}}

    cur, err := userColl.Find(ctx, filterr)
    if err != nil {
        log.Fatal().
            Err(err).
            Msg("err1")
    }

    for cur.Next(context.TODO()) {
        var elem models.Profile
        err := cur.Decode(&elem)
        fmt.Println(elem)
        if err != nil {
            log.Fatal().
                Err(err).
                Msg("err2")
        }
        results = append(results, elem)
    }

    if err := cur.Err(); err != nil {
        log.Fatal().
            Err(err).
            Msg("err3")
    }

    cur.Close(context.TODO())

    return results, nil
}

searchProfiles returns this:

1:
avatar: ""
banner: ""
bio: ""
followerCount: 0
followingCount: 0
likeCount: 0
location: ""
name: ""
protected: false
treatCount: 0
username: "dev"
verified: false

getProfile returns this:

...
profile:Object
username:"dev"
verified:false
protected:false
avatar:""
banner:""
followercount:163
followingcount:15
treatcount:13
likecount:612
name:"developer"
bio:"23, ayooo"
website:""
location:"afk"

Try to add to your Profile model additional description of every parameter that you need returned from db so they match exactly. So if you have your model with parameter 'Name' and in your mongo document it's 'name' than you need to map it with 'bson'. For example:

type Profile struct {
  ***
  Name string `json:"name" bson:"name"`
  TreatCount int32  `json:"treatcount" bson:"treatcount"`
  ***
}

It was how I was appending the data!!

func SearchProfiles(filter string) ([]models.Profile, error) {
    profiles := []models.Profile{}
    user := models.User{}

    filterr := bson.D{{Key: "username", Value: primitive.Regex{Pattern: filter, Options: ""}}}

    cur, err := userColl.Find(ctx, filterr)
    if err != nil {
        log.Fatal().
            Err(err).
            Msg("err1")
    }

    for cur.Next(context.TODO()) {
        err := cur.Decode(&user)
        if err != nil {
            log.Fatal().
                Err(err).
                Msg("err2")
        }
        profiles = append(profiles, user.Profile)
    }

    if err := cur.Err(); err != nil {
        log.Fatal().
            Err(err).
            Msg("err3")
    }

    cur.Close(context.TODO())

    return profiles, nil
}
