Easysearch、Elasticsearch 还是 Opensearch，是个问题

          "type" : "text",

          "analyzer" : "standard"

        }

      }

    }

 
当我执行分词
GET test_name/_analyze
{
  "analyzer": "ik_max_word_pinyin",
  "text": "kk-lin-test"
}
 
下面是分词结果

    },

    {

      "token" : "t",

      "start_offset" : 7,

      "end_offset" : 11,

      "type" : "ENGLISH",

      "position" : 13

    },

    {

      "token" : "test",

      "start_offset" : 7,

      "end_offset" : 11,

      "type" : "ENGLISH",

      "position" : 13

    }

  ]

}

好像是因为kk这个重复了，出现了相同的 start_offset 和 end_offset 但是 position 不同导致的，查了一下资料说要注释掉部分代码重新编译（6.8 版本的一个方案）
 
请问一下有其他的方式可以在 ES层面去解决这个问题嘛？

    排查了好久，发现是settings的一个配置解决的，原settings

                "my_pinyin": {

                    "keep_full_pinyin": true,
    
                    "remove_duplicated_term": true,

                    "keep_original": true,
    
                    "lowercase": true
    
                }   
    
            }
    
        }
    
    }
    
}

    是因为 "keep_original": true 这个配置项引起的，但是具体为什么不知道，去掉这个配置项或者改成false就好了！
