elasticsearch 常用命令（一）

索引 搜索 mapping 分詞器

1.創建索引

http://192.168.65.131:9200/smartom_index?pretty

2.查看索引:

http://192.168.65.131:9200/_cat/indices?v

3.插入數據【這樣也就是說創建了一個文檔為users】

http://192.168.65.131:9200/smartom_index/users/101
{
    "name":"smartom",
    "age":19
}

---

4.精確搜索

http://192.168.65.131:9200/smartom_index/_search?q=name:smartom

5.全詞搜索

http://192.168.65.131:9200/smartom_index/_search

---

全文索引

6.全詞搜索 term

term是代表完全匹配，即不進行分詞器分析，文檔中必須包含整個搜索的詞匯

GET smartom_index/users/_search
{
  "query":{ "term":{ "name":{ "value":"smartom" } } } }

7.全詞搜索 match 全文搜索查詢

分詞查詢

GET smartom_index/users/_search
{
  "query": { "match": { "name": "我是smartom你是誰" } } }

---

分詞器analyze

8.創建一個分詞器

POST _analyze { "analyzer":"standard", "text":"我是smartom你是誰" }

standard

simple

---

過濾器 標記器

9. 一個標記器【filter？】

POST _analyze { "tokenizer":"lowercase", "text":"SMARTOM" }

也可以 在tokenizer里面寫 standard

10.一個過濾器：

POST _analyze { "tokenizer": "standard", "filter": ["lowercase"], "text": "我是smartom你是誰" }

11.字符過濾器：[過濾html代碼]

POST _analyze { "tokenizer": "standard", "char_filter": ["html_strip"], "text": "woshi<br><b>asdf</b>是" }

12.創建一個過濾器：settings analysis analyzer

PUT smartom
{
  "settings": { "analysis": { "analyzer": { "smartom-analyer":{ "type":"custom", "tokenizer":"standard", "char_filter":["html_strip"], "filter":["lowercase"] } } } } }

13.創建倉庫：

前提指定repo路徑 elasticsearch.yml path.repo path.repo:["/home/smartom/Desktop/esbak"]

PUT _snapshot/mybackup
{
  "type": "fs", "settings": { "location": "/home/smartom/Desktop/esbak" } }

14.備份索引：

bak1 是備份名稱 smartom_index 備份的索引名稱

PUT _snapshot/mybackup/bak1?wait_for_completion=true { "indices": "smartom_index" }

15.刪除索引

DELETE smartom

16.關閉索引

POST smartom_index/_close

17.恢復索引

POST _snapshot/mybackup/bak1/_restore?wait_for_completion=true { "indices": "smartom_index" }

18.查看當前插件

GET _cat/plugins

19.查看mapping當前文檔 查看文檔字段類型?

GET smartom_index/_mappings

20.創建mapping

[剛創建的時候]

POST /smartom_index/fulltext/_mapping
{
    "properties": { "content": { "type": "text", "analyzer": "ik_max_word", "search_analyzer": "ik_max_word" } } }

需要導入和導出數據

刪除數據之后 title 用ik分詞器進行索引

PUT smartom_index
{
    "mappings": { "news":{ "properties": { "title": { "type":"text", "analyzer": "ik_max_word" } } } } }

21.修改文檔中的類型？

PUT smartom_index/_mapping/users
{
  "properties": { "news": { "type": "text", "fields": { "keyword": { "type": "keyword", "ignore_above": 256 } } } }
