Elasticsearch 9.3 count endpoint (Ruby example)

Use client.count to get the number of documents matching a query, without returning the documents themselves:

response = client.count(
  index: 'products',
  body: {
    query: { term: { category: 'electronics' } }
  }
)

puts "Electronics: #{response['count']}"

Counting all documents

Omit the body parameter to count all documents in an index:

response = client.count(index: 'products')
puts "Total products: #{response['count']}"

Multiple indices

Pass a comma-separated string or an array of index names to count across multiple indices:

response = client.count(index: ['products', 'orders'])
puts "Total across indices: #{response['count']}"
