Elasticsearch - Advanced Patterns

Given this Elasticsearch query snippet:

{"sort": [{"date": "asc"}], "size": 2, "search_after": ["2023-01-01T00:00:00"]}

What will the query return?

ADocuments including the date 2023-01-01

BDocuments sorted by date descending, starting before 2023-01-01

CDocuments sorted by date ascending, starting after 2023-01-01

DAn error because search_after value is invalid

Step-by-Step Solution

Solution:

Step 1: Analyze the sort and search_after values
The sort is ascending by date, and search_after uses the last date value to start after that point.
Step 2: Understand the effect of search_after
The query returns documents with dates strictly greater than "2023-01-01T00:00:00", limited to 2 documents.
Final Answer:
Documents sorted by date ascending, starting after 2023-01-01 -> Option C
Quick Check:
search_after returns next page after given sort value [OK]

Quick Trick: search_after starts after given sort values, not including them [OK]
