Elasticsearch 在bool查询中使用分词器

1. 创建索引 test setting和mappings

设置了自定义分词映射规则。

PUT /test
{"settings": {"analysis": {"filter": {"my_synonym": {"type": "synonym","updateable": true,"synonyms_path": "dic/synonyms.txt"}},"analyzer": {"my_analyzer": {"tokenizer": "ik_max_word","filter": ["my_synonym"]}}}},"mappings": {"properties": {"name": {"type": "text","analyzer": "ik_max_word"}}}
}

dic/synonyms.txt文件中的映射词如下：

张三,李四 => 王五
电脑 => 计算机
苹果 => 苹果电脑

2. 向test索引中写入数据

PUT test/_doc/1
{"name":"电脑"
}PUT test/_doc/2
{"name":"苹果"
}PUT test/_doc/3
{"name":"王五"
}

3. 查询

使用bool查询数据。

#查询语句
GET test/_search/
{"query": {"bool": {"must": [{"match":{"name":{"query":"张三,李四","analyzer":"my_analyzer"}}}]}}
}#查询结果
{"took" : 831,"timed_out" : false,"_shards" : {"total" : 1,"successful" : 1,"skipped" : 0,"failed" : 0},"hits" : {"total" : {"value" : 1,"relation" : "eq"},"max_score" : 3.257093,"hits" : [{"_index" : "test","_type" : "_doc","_id" : "3","_score" : 3.257093,"_source" : {"name" : "王五"}}]}
}

以上查询中query中指定查询“张三,李四”，同时由于指定了自定义分词映射规则，会自动将“张三,李四”映射为“王五”进行查询，结果所以会查询出“王五”。
