dynamic synonym for ElasticSearch
elasticsearch動態同義詞插件是添加一個同義詞過濾器在給定間隔(默認60秒)來重新加載同義詞文件(本地文件或遠程文件)。
一.下載
根據自身的elasticsearch版本從官網中找到相應版本的源碼:
https://github.com/bells/elasticsearch-analysis-dynamic-synonym/tree/master
這裏版本使用2.3.0
二.安裝
1.mvn package
2.copy and unzip target/releases/elasticsearch-analysis-dynamic-synonym-{version}.zip to your-es-root/plugins/dynamic-synonym
3.修改plugin-descriptor.properties
三.重啓elasticsearch
1.ps -ef | grep elasticsearch
2.kill -9 xxx
3.bin/elasticsearch -d
四.注意事項
在啓動過程中會報和ik或者pinyin分詞器jar包衝突的錯誤，只要刪除掉dynamic synonym裏的jar即可
五.建立索引
crul XPOST 'http://localhost:19200/dstest/'

"settings": {
"index": {
"analysis": {
"analyzer": {
"my_synonym": {
"tokenizer": "whitespace",
