Re-explain

Index Operation (PUT /index/_doc/id):

  • Creates a new document or completely replaces existing one
  • Overwrites the entire document if it exists
  • Always succeeds (creates or replaces)

Create Operation (PUT /index/_create/id):

  • Only creates a new document
  • Fails if document with same ID already exists
  • Returns 409 Conflict error for existing documents
# Index - will replace if exists
PUT /users/_doc/1
{"name": "John", "age": 30}

# Create - will fail if ID 1 exists
PUT /users/_create/2
{"name": "Jane", "age": 25}
