What is missing or incorrect in this percolate query snippet?

{
  "query": {
    "percolate": {
      "field": "stored_query"
    }
  }
}

AThe <code>percolate</code> query cannot be used inside a <code>query</code> context

BThe <code>field</code> name should be <code>query</code> instead of <code>stored_query</code>

CThe query should be wrapped inside a <code>match</code> clause

DThe <code>document</code> parameter is missing, which specifies the document to match

Step-by-Step Solution

Solution:

Step 1: Analyze the percolate query structure
The percolate query requires a document parameter to specify the document to match against stored queries.
Step 2: Check the provided snippet
The snippet only specifies the field but omits the document parameter.
Step 3: Validate other options
The field name can be arbitrary as long as it matches the mapping; wrapping in match is not required; percolate queries are valid inside query.
Final Answer:
The document parameter is missing, which specifies the document to match -> Option D
Quick Check:
Percolate queries must include a document to match [OK]

Quick Trick: Always include 'document' in percolate queries [OK]
