Pinned query [query-dsl-pinned-query]

Promotes selected documents to rank higher than those matching a given query. This feature is typically used to guide searchers to curated documents that are promoted over and above any "organic" matches for a search. The promoted or "pinned" documents are identified using the document IDs stored in the _id field.

Example request [_example_request]

GET /_search
{
  "query": {
    "pinned": {
      "ids": [ "1", "4", "100" ],
      "organic": {
        "match": {
          "description": "iphone"
        }
      }
    }
  }
}

Pin documents in a specific index [_pin_documents_in_a_specific_index]

If you’re searching over multiple indices, you can pin a document within a specific index using docs:

GET /_search
{
  "query": {
    "pinned": {
      "docs": [
        {
          "_index": "my-index-000001", <1>
          "_id": "1"
        },
        {
          "_id": "4" <2>
        }
      ],
      "organic": {
        "match": {
          "description": "iphone"
        }
      }
    }
  }
}

1. The document with id 1 from my-index-000001 will be the first result.
2. When _index is missing, all documents with id 4 from the queried indices will be pinned with the same score.
