中文+拼音+同音字 都存在的情况怎么实现搜索？

"title" : {

    "analyzer" : "by_max_word",

    "type" : "text",

    "fields" : {

      "pinyin" : {

        "search_analyzer" : "by_max_word_pinyin",

        "analyzer" : "by_max_word_pinyin",

        "type" : "text"

      },

      "word" : {

        "search_analyzer" : "no_synonym_standard",

        "analyzer" : "no_synonym_standard",

        "type" : "text"

      }

    }

  }

GET 索引名称或别名/_search

{

  "query": {

    "multi_match": {

      "query": "关键词",

      "fields": [

        "title",

        "title.pinyin",

        "title.word"

        ]

    }

  }, 

  "size": 10

}
