boto3_cloudsearch_examples.py

import boto3

client = boto3.client('cloudsearch')

# List properties of all domains
print "List all domains"
domains = []
response = client.describe_domains()
for domain in response['DomainStatusList']:
    domain_name = domain['DomainName']
    domains.append(domain_name)
    print domain_name

# List properties of specific domains - if you had a domain name
# Assuming there was at least one domain in the response above
domain = domains[0]
print "{}".format(domain)
response = client.describe_domains(DomainNames=[domain])
print "    ARN: {}".format(domain, response['DomainStatusList'][0]['ARN'])

# Describe all index fields of 'domain'
print "    Index Fields:"
response = client.describe_index_fields(DomainName=domain)
fields_info = response['IndexFields']
for field_info in fields_info:
    field_name = field_info['Options']['IndexFieldName']
    field_type = field_info['Options']['IndexFieldType']
    print "        {}: {}".format(field_name, field_type)

Its not able to search domain with Engine Type "CloudSearch (2011 API)". Could you please check and suggest how to use describe_domains(DomainNames=[domain]) with domain names of 2011 API?
