建立索引
from elasticsearch import Elasticsearch
es = Elasticsearch('192.168.1.1:9200')json
mappings = {
"mappings": {
"type_doc_test": { #type_doc_test爲doc_type
"properties": {
"id": {
"type": "long",
"index": "false"
},
"serial": {
"type": "keyword", # keyword不會進行分詞,text會分詞
"index": "false" # 不建索引
},
#tags能夠存json格式,訪問tags.content
"tags": {
"type": "object",
"properties": {
"content": {"type": "keyword", "index": True},
"dominant_color_name": {"type": "keyword", "index": True},
"skill": {"type": "keyword", "index": True},
}
},
"hasTag": {
"type": "long",
"index": True
},
"status": {
"type": "long",
"index": True
},
"createTime": {
"type": "date",
"format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
},
"updateTime": {
"type": "date",
"format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd||epoch_millis"
}
}
}
}
}數據結構
res = es.indices.create(index = 'index_test',body =mappings)
經過以上代碼便可建立es索引app
寫入一條數據
寫入數據須要根據 建立的es索引類型對應的數據結構寫入:dom
from elasticsearch import Elasticsearchelasticsearch
es = Elasticsearch('192.168.1.1:9200')orm
action ={
"id": "1111122222",
"serial":"版本",
#如下tags.content是錯誤的寫法
#"tags.content" :"標籤2",
#"tags.dominant_color_name": "域名的顏色黃色",
#正確的寫法以下:
"tags":{"content":"標籤3","dominant_color_name": "域名的顏色黃色"},
#按照字典的格式寫入,若是用上面的那種寫法,會直接寫成一個tags.content字段。
#而不是在tags中content添加數據,這點須要注意
"tags.skill":"分類信息",
"hasTag":"123",
"status":"11",
"createTime" :"2018-2-2",
"updateTime":"2018-2-3",
}
es.index(index="index_test",doc_type="doc_type_test",body = action)
便可寫入一條數據
錯誤的寫入索引
正確的寫入get
寫入多條數據
from elasticsearch import Elasticsearch
from elasticsearch.helpers import bulk域名
es = Elasticsearch('192.168.1.1:9200')it
ACTIONS = []
action1 ={
"_index": "indes_test",
"_type": "doc_type_test",
"_id":"bSlegGUBmJ2C8ZCSC1R1",
"_source":{
"id": "1111122222",
"serial":"版本",
"tags.content" :"標籤2",
"tags.dominant_color_name": "域名的顏色黃色",
"tags.skill":"分類信息",
"hasTag":"123",
"status":"11",
"createTime" :"2018-2-2",
"updateTime":"2018-2-3",
}
}
action2 ={
"_index": "indes_test",
"_type": "doc_type_test",
"_id":"bSlegGUBmJ2C8ZCSC1R2",
"_source":{
"id": "1111122222",
"serial":"版本",
"tags.content" :"標籤2",
"tags.dominant_color_name": "域名的顏色黃色",
"tags.skill":"分類信息",
"hasTag":"123",
"status":"11",
"createTime" :"2018-2-2",
"updateTime":"2018-2-3",
}
}
ACTIONS.append(action1)
ACTIONS.append(action2)
res,_ =bulk(es, ACTIONS, index="indes_test", raise_on_error=True)
print(res)
這個方式是手動指定了id,若是把」_id」這個參數去掉便可自動生成id數據.
以下:
action2 ={
"_index": "indes_test",
"_type": "doc_type_test",
"_source":{
"id": "1111122222",
"serial":"版本",
"tags.content" :"標籤2",
"tags.dominant_color_name": "域名的顏色黃色",
"tags.skill":"分類信息",
"hasTag":"123",
"status":"11",
"createTime" :"2018-2-2",
"updateTime":"2018-2-3",
}
}
刪除一條數據
from elasticsearch import Elasticsearch
es = Elasticsearch('192.168.1.1:9200')
res = es.delete(index="index_test",doc_type="doc_type_test", id ="bSlegGUBmJ2C8ZCSC1R1")
print(res)
直接替換id的便可刪除所需的id
查詢一條數據
from elasticsearch import Elasticsearch
es = Elasticsearch('192.168.1.1:9200')
res = es.get(index="index_test",doc_type="doc_type_test", id ="bSlegGUBmJ2C8ZCSC1R2")
print(res)
直接替換id的便可查詢所需的id
查詢全部數據
from elasticsearch import Elasticsearch
es = Elasticsearch('192.168.1.1:9200')
res = es.search(index="index_test",doc_type="doc_type_test")
print(res)
print(res['hits']['hits'])
經過['hits']參數,能夠解析出查詢數據的詳細內容
根據關鍵詞查找
from elasticsearch import Elasticsearch
es = Elasticsearch('192.168.1.1:9200')
doc = {
"query": {
"match": {
"_id": "aSlZgGUBmJ2C8ZCSPVRO"
}
}
}
res = es.search(index="index_test",doc_type="doc_type_test",body=doc) print(res)
