中文分词+拼音分词无法生成一些相关的词汇拼音全拼

es版本：7.6.2 语言：php

这是自定义分词：

                    "analysis"=>[
                        "analyzer"=>[
                          "my_analyzer"=>[
                             "type"=>"custom",
                            "tokenizer"=>"ik_max_word",
                            "filter"=>"my_filter"
                          ]
                        ],
                        "filter"=>[
                          "my_filter"=>[
                            "type"=>"pinyin",
                            "first_letter" => "prefix",
                            "padding_char" => "",
                            "keep_separate_first_letter"=>false,
                            "keep_full_pinyin"=>true,
                            "keep_original"=>true,
                            "limit_first_letter_length"=>16,
                            "lowercase"=>true,
                            'keep_first_letter'=>true,
                            "remove_duplicated_term"=>true,
                            "keep_joined_full_pinyin"=>true  #这里设置为true
                          ]
                        ]
                    ],

搜索词为”腾讯“它会返回：

            "type": "CN_CHAR",
            "position": 1
        }
    ]
}

就是不生成微信的全拼，导致输入”“搜索不到，中间加个空格就可以了”wei xin“，不止微信还有钉钉，微博等词。

我尝试修改的源码但未生效

不知道哪里的问题导致一些词无法生成全拼
