Match All Query

The simplest query is _match_all, which matches all documents, returns all documents in any given database giving them all a weight of 0.0:

Example

SEARCH /bank/

{
  "_query": {
    "_match_all": {}
  }
}

Match None Query

The query _match_none is the inverse of the _match_all query, and matches no documents.

Example

SEARCH /bank/

{
  "_query": {
    "_match_none": {}
  }
}
