func main() {

    match, _ := regexp.MatchString("p([a-z]+)ch", "peach")
    fmt.Println(match)

    r, _ := regexp.Compile("p([a-z]+)ch")

    fmt.Println(r.MatchString("peach"))
    fmt.Println(r.FindStringIndex("peach punch"))

    fmt.Println(r.FindStringSubmatch("peach punch"))

    fmt.Println(r.FindStringSubmatchIndex("peach punch"))
}
