建议先安装kibana 参考 kibana-6-8-4 win 安装
一、安装
elasticsaerch目录下的plugins新建ik目录
下载的ik解压至该目录
二、验证
以下操作均在kibana的“Dev Tools”
1、创建索引（相当于创建数据库及表结构）
索引名：article
字段:title,content
PUT article
{
"mappings": {
"_doc": {
"properties": {
"title": {
"type": "text",
"analyzer": "ik_max_word",
"search_analyzer": "ik_smart"
},
"content": {
"type": "text",
"analyzer": "ik_max_word",
"search_analyzer": "ik_smart"
}
}
}
}
}
2、插入数据
POST /article/_doc/?pretty
{
"title": "Elasticsearch 6.x Mapping设置",
"content":" Mapping,映射,相当于关系型数据库创建语句,定义文档字段及其类型、索引与存储方式"
}
3、查询刚刚插入的数据
GET /article/_search?q=*
4、IK查询并高亮
GET /article/_search
{
"query" : { "match" : { "content" : "数据库" }},
"highlight" : {
"pre_tags" : ["<em>"],
"post_tags" : ["</em>"],
"fields" : {
"content" : {}
}
}
}
三、ik中ik_max_word和ik_smart区别
ik_max_word：最细粒度拆分，ik_smart：最粗粒度
POST /_analyze
{
"text":"中华人民共和国人民大会堂",
"analyzer":"ik_max_word"
}
返回
{
"tokens" : [
{
"token" : "中华人民共和国",
"start_offset" : 0,

"position" : 0
