当使用Elasticsearch API时，我们可以使用各种HTTP方法（如GET、POST、PUT、DELETE）来与Elasticsearch进行交互。以下是一些常用的Elasticsearch API示例（python）：

1. 创建索引：

# python
from elasticsearch import Elasticsearch

es = Elasticsearch()

index_name = "my_index"

# 创建索引
es.indices.create(index=index_name)

2. 索引文档：

from elasticsearch import Elasticsearch

es = Elasticsearch()

index_name = "my_index"
document = {
"title": "Example Document",
"content": "This is an example document."
}

# 索引文档
es.index(index=index_name, body=document)

3. 搜索文档：

from elasticsearch import Elasticsearch

es = Elasticsearch()

index_name = "my_index"
query = {
    "query": {
          "match": {
               "content": "example"
               }
          }
    }

# 搜索文档
response = es.search(index=index_name, body=query)

4. 删除索引：

from elasticsearch import Elasticsearch

es = Elasticsearch()

index_name = "my_index"

# 删除索引
es.indices.delete(index=index_name)
