Before the Documents function was introduced, you needed to create an index just to facilitate retrieving documents from a collection. See the Indexing tutorials for details.

Parameters

Parameter Type Definition and Requirements

collection

Reference

A Reference to the collection from which documents should be collected.

Returns

A Set Reference which represents all of the documents in the specified collection.

Examples

The following query returns three documents in the Letters collection (established as part of the Index tutorials):

client.query(
  q.Paginate(q.Documents(q.Collection('Letters')), { size: 3 })
)
.then((ret) => console.log(ret))
.catch((err) => console.error(
  'Error: [%s] %s: %s',
  err.name,
  err.message,
  err.errors()[0].description,
))

  data:
   [ Ref(Collection("Letters"), "101"),
     Ref(Collection("Letters"), "102"),
     Ref(Collection("Letters"), "103") ] }
result = client.query(
  q.paginate(q.documents(q.collection('Letters')), size=3)
)
print(result)
