How to create request body for Python Elasticsearch mSearch

How to create request body for Python Elasticsearch mSearch

To create a request body for a multi-search (mSearch) request using the Python Elasticsearch library, you need to structure the request as a list of dictionaries. Each dictionary represents an individual search request within the mSearch request. Here's an example of how to create a request body for an mSearch using the Elasticsearch library:

from elasticsearch import Elasticsearch # Connect to Elasticsearch es = Elasticsearch() # Define your individual search queries search_query1 = { "index": "your_index_name", "query": { "match": { "field1": "value1" } } } search_query2 = { "index": "your_index_name", "query": { "range": { "field2": {"gte": 100} } } } # Create the mSearch request body as a list of dictionaries msearch_body = [search_query1, search_query2] # Perform the mSearch request response = es.msearch(body=msearch_body) # Process the response for i, result in enumerate(response['responses']): print(f"Response for query {i+1}:") print(result)

In this example:

  • search_query1 and search_query2 are dictionaries representing the individual search queries you want to include in the mSearch request.
  • The msearch_body is a list that contains these individual search queries.
  • The es.msearch() method sends the mSearch request to Elasticsearch with the specified body.
  • The response object contains the response for each individual search query in the order they were provided in the msearch_body.

Remember to customize the search_query1 and search_query2 dictionaries to match your actual search criteria and index names.

Also, make sure you have the Elasticsearch Python library (elasticsearch) installed in your environment using the following command:

pip install elasticsearch
