ArangoDB: Get documents by keys

‘collection.documents(keys)’ method takes array of keys as arguments and return all the documents associated with these keys. If a document is not exist with given key, then it is excluded from the result.

 

Let’s experiment it with example.

127.0.0.1:8529@abc_org> db.user.toArray()
[ 
  { 
    "_key" : "17089", 
    "_id" : "user/17089", 
    "_rev" : "_cRe1GKq---", 
    "id" : 1, 
    "firstName" : "Sailu", 
    "lastName" : "Ptr", 
    "age" : 32 
  }, 
  { 
    "_key" : "17091", 
    "_id" : "user/17091", 
    "_rev" : "_cRe1GKu---", 
    "id" : 2, 
    "firstName" : "Gopi", 
    "lastName" : "Battu", 
    "age" : 33 
  }, 
  { 
    "_key" : "17093", 
    "_id" : "user/17093", 
    "_rev" : "_cRe1GKy---", 
    "id" : 3, 
    "firstName" : "Krishna", 
    "lastName" : "Gurram", 
    "age" : 32 
  }, 
  { 
    "_key" : "17095", 
    "_id" : "user/17095", 
    "_rev" : "_cRe1H-6---", 
    "id" : 4, 
    "firstName" : "Venkat", 
    "lastName" : "Ptr", 
    "age" : 35 
  } 
]

 

Example: Get all the documents with keys "17095", "17093", "18907".

127.0.0.1:8529@abc_org> db.user.documents(["17095", "17093", "18907"])
{ 
  "documents" : [ 
    { 
      "_key" : "17093", 
      "_id" : "user/17093", 
      "_rev" : "_cRe1GKy---", 
      "id" : 3, 
      "firstName" : "Krishna", 
      "lastName" : "Gurram", 
      "age" : 32 
    }, 
    { 
      "_key" : "17095", 
      "_id" : "user/17095", 
      "_rev" : "_cRe1H-6---", 
      "id" : 4, 
      "firstName" : "Venkat", 
      "lastName" : "Ptr", 
      "age" : 35 
    } 
  ] 
}
