步骤三：使用同义词搜索

Elasticsearch 7.x之前的版本和之后的版本，命令有差别，所以分开举例。

7.x之前的版本

创建索引“myindex”，配置分词策略。

PUT myindex{  "settings": {    "analysis": {      "filter": {        "my_synonym": {          "type": "dynamic_synonym"        }      },      "analyzer": {        "ik_synonym": {          "filter": [            "my_synonym"          ],          "type": "custom",          "tokenizer": "ik_smart"        }      }    }  },  "mappings": {    "mytype" :{      "properties": {        "desc": {          "type": "text",          "analyzer": "ik_synonym"        }      }    }  }}

导入数据，将文本信息导入“myindex”索引中。

PUT /myindex/mytype/1{    "desc": "我今天获奖了我很开心"}

使用同义词“高兴”进行文本搜索，并查看搜索结果。

GET /myindex/_search{  "query": {    "match": {      "desc": "高兴"    }  }}

搜索结果：

{  "took" : 2,  "timed_out" : false,  "_shards" : {    "total" : 5,    "successful" : 5,    "skipped" : 0,    "failed" : 0  },  "hits" : {    "total" : 1,    "max_score" : 0.49445358,    "hits" : [      {        "_index" : "myindex",        "_type" : "mytype",        "_id" : "1",        "_score" : 0.49445358,        "_source" : {          "desc" : "我今天获奖了我很开心"        }      }    ]  }}

7.x及之后的版本

创建索引“myindex”，配置分词策略。

PUT myindex{    "settings": {        "analysis": {            "filter": {                "my_synonym": {                    "type": "dynamic_synonym"                }            },            "analyzer": {                "ik_synonym": {                    "filter": [                        "my_synonym"                    ],                    "type": "custom",                    "tokenizer": "ik_smart"                }            }        }    },    "mappings": {        "properties": {            "desc": {                "type": "text",                "analyzer": "ik_synonym"            }        }    }}

导入数据，将文本信息导入“myindex”索引中。

PUT /myindex/_doc/1{    "desc": "我今天获奖了我很开心"}

使用同义词“高兴”进行文本搜索，并查看搜索结果。

GET /myindex/_search{  "query": {    "match": {      "desc": "高兴"    }  }}

搜索结果：

{  "took" : 1,  "timed_out" : false,  "_shards" : {    "total" : 1,    "successful" : 1,    "skipped" : 0,    "failed" : 0  },  "hits" : {    "total" : {      "value" : 1,      "relation" : "eq"    },    "max_score" : 0.1519955,    "hits" : [      {        "_index" : "myindex",        "_type" : "_doc",        "_id" : "1",        "_score" : 0.1519955,        "_source" : {          "desc" : "我今天获奖了我很开心"        }      }    ]  }}
