[Solved] You wrote this Elasticsearch query to paginate results: { "size": 10, "sort": [{"date": "desc"}], "search_after": "2023-01-01T00:00:00" } But it returns an error. What is the likely cause? | Elasticsearch

Elasticsearch - Advanced Patterns

You wrote this Elasticsearch query to paginate results:

{
  "size": 10,
  "sort": [{"date": "desc"}],
  "search_after": "2023-01-01T00:00:00"
}

But it returns an error. What is the likely cause?

Asize cannot be 10 with search_after

Bsearch_after value must be an array, not a string

Csort order must be ascending for search_after

Ddate field cannot be used in sort

Step-by-Step Solution

Solution:

Step 1: Check the type of search_after value
The search_after parameter requires an array of values, but here it is a string.
Step 2: Identify the error cause
Passing a string instead of an array causes a syntax error in the query.
Final Answer:
search_after value must be an array, not a string -> Option B
Quick Check:
search_after requires array input [OK]

Quick Trick: Always wrap search_after values in an array [OK]
