Elasticsearch - Advanced Patterns

A{"scroll_id": "DXF1ZXJ5QW5kRmV0Y2gBAAAAAAA", "size": 100}

B{"query": {"match_all": {}}, "scroll": "1m", "size": 100}

C{"query": {"match": {"field": "value"}}, "timeout": "1m"}

D{"scroll": "1m", "update": true}

Step-by-Step Solution

Solution:

Step 1: Identify scroll search syntax
Starting a scroll requires a query, a scroll time, and size for batch size.
Step 2: Analyze options
{"query": {"match_all": {}}, "scroll": "1m", "size": 100} includes query, scroll time, and size correctly. {"scroll_id": "DXF1ZXJ5QW5kRmV0Y2gBAAAAAAA", "size": 100} uses scroll_id which is for continuing scroll, not starting. {"query": {"match": {"field": "value"}}, "timeout": "1m"} lacks scroll parameter. {"scroll": "1m", "update": true} has invalid update field.
Final Answer:
{"query": {"match_all": {}}, "scroll": "1m", "size": 100} -> Option B
Quick Check:
Start scroll = query + scroll + size [OK]

Quick Trick: Start scroll with query + scroll + size keys [OK]
