OpenSearch

OpenSearch is the flexible, scalable, open-source way to build solutions for data-intensive applications. Explore, enrich, and visualize your data with built-in performance, developer-friendly tools, and powerful integrations for machine learning, data processing, and more.

Connect

from opensearchpy import OpenSearch

host = 'localhost'
port = 9200
auth = ('admin', 'Open@159x357')

# Initialize the OpenSearch client
client = OpenSearch(
    hosts=[{'host': host, 'port': port}],
    http_compress=True,
    http_auth=auth,
    use_ssl=True,
    verify_certs=False,
    ssl_show_warn=False
)

response = client.cluster.health()
print(response)

Index

Create

# Create an index with non-default settings.
index_name = 'INDEX_NAME'
index_body = {
  'settings': {
    'index': {
      'number_of_shards': 1,
      'number_of_replicas': 1
    }
  }
}

response = client.indices.create(index_name, body=index_body)
print(response)

Insert

TIP

If you do not provide a key, openserach will create on for you

document_body = {
    'key1': value1,
    'key2': value2,
    'key3': value3
}

try:
    response = client.index(
        index='INDEX_NAME',
        body=document_body,
        refresh=True
    )
    print(f"Indexed document ID: {response['_id']}")
except Exception as e:
    print(f"Error indexing document: {e}")
