python中的Elasticsearch操作

导入包

from elasticsearch import Elasticsearch

本地连接

es = Elasticsearch(['127.0.0.1:9200'])

创建索引

es.indices.create(index="python_es01",ignore=400)

ingore=400 ingore是忽略的意思，400是未找到

删除索引

es.indices.delete(index="python_es01")

检查索引是否存在

es.indices.exists(index="python_es01")

插入数据

es.index(index="python_es01",doc_type="doc",id=1,body={"name":"kitty","age":50})

同时也可以不加id,即

es.index(index="python_es01",doc_type="doc",body={"name":"kitty","age":10})

查询操作

按id查询

result = es.get(index="python_es01",doc_type="doc",id=1)

会有一个返回值

全查

body= {
"query":{
"match_all":{}
}
}
result = es.search(index="python_es01",body=body)

使用id的用GET，其他search

删除操作

result = es.delete(index="goods",doc_type="type1",id=2)

按查询结果删除

result = es.delete_by_query(index="goods",body=body)

建立mapping

body = {
"mappings": {
"properties": {
"name": {
"type": "text"
},
"price": {
"type": "long"
}
}
}
}
result = es.indices.create(index="shang",body=body)
