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. See the Elasticsearch documentation on pinned query for more details.
