ElasticSearch 学习笔记
ElasticSearch 学习笔记 安装中文分词插件 docker exec -it elasticsearch bash $ elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v8.4.1/elasticsearch-analysis-ik-8.4.1.zip Dev Tools content 类型为 text，写入时使用 ik_max_word 做分词，搜索时使用 ik_smart 分词。这两个的区别在于，前者产生尽可能多的分词，后者产生粗粒度的分词。 PUT /words { "mappings": { "properties": { "content": { "type": "text", "analyzer": "ik_max_word", "search_analyzer": "ik_smart" }, "age": { "type": "integer", "index": false } } } } { "acknowledged": true, "shards_acknowledged": true, "index": "words" }
