拼音分词 + IK分词混合使用

创建索引，配置两种分词器

PUT /blog/
{
    "settings":{
        "number_of_shards": 3,
        "number_of_replicas": 1,
        "analysis": {
            "analyzer": {
                "default":{
                    "tokenizer":"ik_max_word"
                },                
                "pinyin_analyzer": {
                    "type": "custom",
                    "tokenizer": "my_pinyin",
                    "filter": ["word_delimiter"]
                }
            },
            "tokenizer": {
                "my_pinyin" : {
                      "type" : "pinyin",
                      "keep_first_letter":true,
                      "keep_separate_first_letter" : false,
                      "keep_full_pinyin" : true,
                      "keep_original" : false,
                      "limit_first_letter_length" : 16,
                      "lowercase" : true
                  }
            }
        }
    }
}

针对索引配置字段映射

{    
    "properties" : {
        "title" : {
            "type" : "text",
            "analyzer" : "ik_max_word",
            "fields" : {
                "pinyin" : {
                    "type" : "text",
                    "term_vector" : "with_positions_offsets",
                    "analyzer" : "pinyin_analyzer",
                    "boost" : 10
                  }
             }
        },      
        "content":{
          "type":"text",
          "analyzer" : "ik_max_word"
        },
        "author":{
          "type":"text",
          "analyzer" : "ik_max_word"
        },
        "keyword":{
          "type":"text",
          "analyzer" : "ik_max_word"
        },
        "createtime":{            
            "type":"date",            
            "format":"yyyy-MM-dd HH:mm:ss || yyyy-MM-dd || epoch_millis"    
        }
    }
}

检查自定义的词语分析器是否生效

      "type" : "word",
      "position" : 0
    },
    {
      "token" : "ldh",
      "start_offset" : 0,

    {
      "token" : "de",
      "start_offset" : 0,
      "end_offset" : 0,
      "type" : "word",
      "position" : 1
    },
    {

      }
    ]
  }
}

通过 validate-query API 可以帮助理解查询是如何执行的

GET /blog/article/_validate/query?explain
{
  "query": {
    "multi_match": {
      "type":"most_fields",
      "query":"王者rongyao",
      "fields":["title", "title.pinyin"]
    }
  }
}

返回值

{
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "failed" : 0
  },
  "valid" : true,
  "explanations" : [
    {
      "index" : "blog",
      "valid" : true,
      "explanation" : "+((title:王者 title:rongyao) | ((title.pinyin:wang)^10.0 (title.pinyin:zhe)^10.0 (title.pinyin:rong)^10.0 Synonym(title.pinyin:wzrongyao title.pinyin:yao)))~1.0 #*:*"
    }
  ]
