索引 搜索 mapping 分词器
1.创建索引
http://192.168.65.131:9200/smartom_index?pretty2.查看索引:
http://192.168.65.131:9200/_cat/indices?v3.插入数据【这样也就是说创建了一个文档为users】
http://192.168.65.131:9200/smartom_index/users/101
{
"name":"smartom",
"age":19
}4.精确搜索
http://192.168.65.131:9200/smartom_index/_search?q=name:smartom5.全词搜索
http://192.168.65.131:9200/smartom_index/_search全文索引
6.全词搜索 term
term是代表完全匹配，即不进行分词器分析，文档中必须包含整个搜索的词汇
GET smartom_index/users/_search
{
"query":{
"term":{
"name":{
"value":"smartom"
}
}
}
}7.全词搜索 match 全文搜索查询
分词查询
GET smartom_index/users/_search
{
"query": {
"match": {
"name": "我是smartom你是谁"
}
}
}分词器analyze
8.创建一个分词器
POST _analyze
{
"analyzer":"standard",
"text":"我是smartom你是谁"
}standard
simple
过滤器 标记器
9. 一个标记器【filter？】
POST _analyze
{
"tokenizer":"lowercase",
"text":"SMARTOM"
}也可以 在tokenizer里面写 standard
10.一个过滤器：
POST _analyze
{
"tokenizer": "standard",
"filter": ["lowercase"],
"text": "我是smartom你是谁"
}11.字符过滤器：[过滤html代码]
POST _analyze
{
"tokenizer": "standard",
"char_filter": ["html_strip"],
"text": "woshi<br><b>asdf</b>是"
}12.创建一个过滤器：settings analysis analyzer
PUT smartom
{
"settings": {
"analysis": {
"analyzer": {
"smartom-analyer":{
"type":"custom",
"tokenizer":"standard",
"char_filter":["html_strip"],
"filter":["lowercase"]
}
}
}
}
}13.创建仓库：
前提指定repo路径 elasticsearch.yml path.repo path.repo:["/home/smartom/Desktop/esbak"]
PUT _snapshot/mybackup
{
"type": "fs",
"settings": {
"location": "/home/smartom/Desktop/esbak"
}
}14.备份索引：
bak1 是备份名称 smartom_index 备份的索引名称
PUT _snapshot/mybackup/bak1?wait_for_completion=true
{
"indices": "smartom_index"
}15.删除索引
DELETE smartom16.关闭索引
POST smartom_index/_close17.恢复索引
POST _snapshot/mybackup/bak1/_restore?wait_for_completion=true
{
"indices": "smartom_index"
}18.查看当前插件
GET _cat/plugins19.查看mapping当前文档 查看文档字段类型?
GET smartom_index/_mappings20.创建mapping
[刚创建的时候]
POST /smartom_index/fulltext/_mapping
{
"properties": {
"content": {
"type": "text",
"analyzer": "ik_max_word",
"search_analyzer": "ik_max_word"
}
}
}需要导入和导出数据
删除数据之后 title 用ik分词器进行索引
PUT smartom_index
{
"mappings": {
"news":{
"properties": {
"title": {
"type":"text",
"analyzer": "ik_max_word"
}
}
}
}
}21.修改文档中的类型？
PUT smartom_index/_mapping/users
{
"properties": {
"news": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword",
"ignore_above": 256
}
}
}
}
