ik分詞器github網址：https://github.com/medcl/elasticsearch-analysis-ik
可參考該網頁內容進行安裝
1、獲取分詞的依賴包
通過git clone https://github.com/medcl/elasticsearch-analysis-ik，下載分詞器源碼
2、進入源碼目錄，將代碼進行打包
打包需要用到jdk，故在安裝ik分詞器之前需要安裝jdk
mvn clean package
以上命令進行打包
在當前目錄下生成了target目錄，打包好的資源都在該目錄下
3、拷貝打包好的資源至ES插件目錄下
cp target/releases/elasticsearch-analysis-ik-{version}.zip your-es-root/plugins/ik
去到your-es-root/plugins/ik目錄，解壓資源包
unzip elasticsearch-analysis-ik-{version}.zip
4、重啓ES
5、測試ik分詞器是否安裝成功
1、創建一個索引，名爲index。
curl -XPUT http://localhost:9200/index
2、爲索引index創建mapping。
curl -XPOST http://localhost:9200/index/fulltext/_mapping -d'
{
"fulltext": {
"_all": {
"analyzer": "ik"
},
"properties": {
"content": {
"type" : "string",
"boost" : 8.0,
"term_vector" : "with_positions_offsets",
"analyzer" : "ik",
"include_in_all" : true
}
}
}
}'
3、測試
curl 'http://localhost:9200/index/_analyze?analyzer=ik&pretty=true' -d '
{
"text":"世界如此之大"
}'
顯示結果如下：
{
"tokens" : [ {
"token" : "text",
"start_offset" : 4,
"end_offset" : 8,
"type" : "ENGLISH",
"position" : 1
}, {
"token" : "世界",
"start_offset" : 11,
"end_offset" : 13,
"type" : "CN_WORD",
"position" : 2
}, {
"token" : "如此",
"start_offset" : 13,
"end_offset" : 15,
"type" : "CN_WORD",
"position" : 3
}, {
"token" : "之大",
"start_offset" : 15,
"end_offset" : 17,
"type" : "CN_WORD",
"position" : 4
} ]
}
