給索引創(chuàng)建映射報錯

{

"error":{

"root_cause":[

{

"type":"mapper_parsing_exception",

"reason":"analyzer [ik_max_word] not found for field [title]"

}

],

"type":"mapper_parsing_exception",

"reason":"analyzer [ik_max_word] not found for field [title]"

},

"status":400

}

原因

未安裝ik分詞插件

解決辦法

安裝分詞插件

./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v6.3.2/elasticsearch-analysis-ik-6.3.2.zip

注意

ik分詞和es的版本要保持一致，不然安裝分詞插件的時候會報錯如下錯誤

Exception in thread "main" java.lang.IllegalArgumentException: Plugin [analysis-ik] was built for Elasticsearch version 6.3.0 but version 6.3.2 is running

啟動ES加載插件

./bin/elasticsearch &
