        // set the caseSensitive to false
        processor.SetCaseSenstive(false)

        processor.AddKeywordAndName("java", "JavaEE")

        res := processor.ExtractKeywords("Hi, I love go, I like python and java", &flashtext.Option{Longest: true})
        for _, result := range res {
            fmt.Println(result.Keyword, "is met in the start position", result.StartIndex)
