给索引创建映射报错

{

"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

未安装ik分词插件

解决办法

安装分词插件

./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分词和es的版本要保持一致，不然安装分词插件的时候会报错如下错误

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
