前一篇文章说了IK中文分词,其实想实现的目的,就是拼音和中文都搜索到东西。类似百度搜索框的输入提示,淘宝搜索框的输入提示。

1,安装配置analysis-pinyin

//下载
$ git clone https://github.com/medcl/elasticsearch-analysis-pinyin.git
$ cd elasticsearch-analysis-pinyin
$ git branch -a
* master //主分支是6.2.3,对应 es6.2.3
 remotes/origin/0.16.x
 remotes/origin/1.x
 remotes/origin/2.x
 remotes/origin/5.3.x
 remotes/origin/5.x
 remotes/origin/6.1.x
 remotes/origin/HEAD -> origin/master
 remotes/origin/master

$ mvn package  //打包

$ ll target/releases/
total 4400
drwxr-xr-x 3 zhangying staff 102 4 24 13:46 ./
drwxr-xr-x 11 zhangying staff 374 4 24 13:32 ../
-rw-r--r-- 1 zhangying staff 4501993 4 24 13:32 elasticsearch-analysis-pinyin-6.2.3.zip

$ cd target/releases/ && unzip elasticsearch-analysis-pinyin-6.2.3.zip

$ brew info elasticsearch
elasticsearch: stable 6.2.3, HEAD

To have launchd start elasticsearch now and restart at login:
 brew services start elasticsearch
Or, if you don't want/need a background service you can just run:
 elasticsearch

//将mvn后的插件copy到es插件目录
$ mv elasticsearch /usr/local/var/elasticsearch/plugins/pinyin

$ elasticsearch  //启动

2,测试pinyin分词

2.1,测试分词

$ curl -XPOST 'http://localhost:9200/pinyin/_analyze?pretty=true' -H 'Content-Type: application/json' -d '
> {
> "analyzer":"pinyin",
> "text":"gaotie"
> }'
{
 "tokens" : [
 {
 "token" : "gao",
 "start_offset" : 0,
 "end_offset" : 0,
 "type" : "word",
 "position" : 0
 },
 {
 "token" : "gaotie",
 "start_offset" : 0,
 "end_offset" : 0,
 "type" : "word",
 "position" : 0
 },
 {
 "token" : "tie",
 "start_offset" : 0,
 "end_offset" : 0,
 "type" : "word",
 "position" : 1
 }
 ]
}

$ curl -XPOST 'http://localhost:9200/pinyin/_analyze?pretty=true' -H 'Content-Type: application/json' -d '
> {
> "analyzer":"pinyin",
> "text":"高铁"
> }'
{
 "tokens" : [
 {
 "token" : "gao",
 "start_offset" : 0,
 "end_offset" : 0,
 "type" : "word",
 "position" : 0
 },
 {
 "token" : "gt",
 "start_offset" : 0,
 "end_offset" : 0,
 "type" : "word",
 "position" : 0
 },
 {
 "token" : "tie",
 "start_offset" : 0,
 "end_offset" : 0,
 "type" : "word",
 "position" : 1
 }
 ]
}

从上面可以看出,pinyin分词对pinyin和中文都能分的,并且分出来的结果还不一样。

2.2,创建索引,mapping,插入数据

curl -XPUT "http://127.0.0.1:9200/pinyin?pretty"
curl -XPOST "http://127.0.0.1:9200/pinyin/test/_mapping?pretty" -H "Content-Type: application/json" -d '
{
    "test": {
            "_all":{
              "enabled":false
            },
            "properties": {
                "id": {
                    "type": "integer"
                },
                "username": {
                    "type": "text",
                    "analyzer": "pinyin"
                },
                "description": {
                    "type": "text",
                    "analyzer": "pinyin"
                }
            }
        }
  }
'
curl -XPOST "http://127.0.0.1:9200/pinyin/test/?pretty"  -H "Content-Type: application/json" -d '
{
    "id" : 1,
    "username" :  "中国高铁速度很快",
    "description" :  "如果要修改一个字段的类型"
}'

curl -XPOST "http://127.0.0.1:9200/pinyin/test/?pretty"   -H "Content-Type: application/json" -d '
{
    "id" : 2,
    "username" :  "动车和复兴号,都属于高铁",
    "description" :  "现在想要修改为string类型"
}'

2.3,全拼音测试

$ curl -XPOST "http://127.0.0.1:9200/pinyin/test/_search?pretty"  -H "Content-Type: application/json"  -d '
> {

>         }
>     }
> }

{
  "took" : 13,
  "timed_out" : false,
  "_shards" : {
    "total" : 5,
    "successful" : 5,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : 2,
    "max_score" : 0.4039931,
    "hits" : [
      {
        "_index" : "pinyin",
        "_type" : "test",
        "_id" : "TGZ2AWMBlEkarXCPb7ED",
        "_score" : 0.4039931,
        "_source" : {
          "id" : 1,
          "username" : "中国高铁速度很快",
          "description" : "如果要修改一个字段的类型"
        }
      },
      {

          "description" : "现在想要修改为string类型"
        }
      }
    ]
  }
}

2.3,拼音分词,汉字搜索

$ curl -XPOST "http://127.0.0.1:9200/pinyin/test/_search?pretty"  -H "Content-Type: application/json"  -d '
> {
>     "query": {

          "description" : "现在想要修改为string类型"
        }
      }
    ]

3,拼音分词和中文分词混合使用
