	Age   int    `lookup:"age" operator:"$gt"`

}

func main() {
	filter := SampleFilter{
		Name:  "John",
		Age:   30,
		Adult: true,
	}
	builder := filterbuilder.NewBuilder()
	query, err := builder.BuildQuery(filter)
	if err != nil {
		fmt.Println(err)
	}
	expected := bson.M{
		"name":  bson.M{"$regex": "John"},
		"age":   bson.M{"$gt": 30},
		"adult": bson.M{"$eq": true},
