.vectors.remove algorithm

The .vectors.remove algorithm is used to remove the embedding from a node.

.vectors.remove  syntax

CALL neptune.algo.vectors.remove(
  [a list of one or more nodes]
)
YIELD node, success
RETURN node, success

.vectors.remove  input

  • a target node list   (required)   –   type: Node[] or NodeId[].

    The node(s) from which you want to remove the embedding. If an empty list is supplied, the result will be empty.

.vectors.remove  outputs

The following outputs are returned for each target node, and if the node has an embedding, the embedding is removed:

  • node   –   The target node.

  • success   –   A Boolean value: true indicates that the removal succeded for the node, and false indicates that it failed.

.vectors.remove  query examples

CALL neptune.algo.vectors.remove( ["person933"] )
YIELD node, success
RETURN node, success
MATCH (n: Student)
CALL neptune.algo.vectors.remove(n)
YIELD status
RETURN n, success

Sample  .vectors.remove  output

Here is an example of the output returned by .vectors.remove when run against the sample Wikipedia dataset using the following query:

aws neptune-graph execute-query \
  --graph-identifier ${graphIdentifier} \
  --query-string "MATCH (n {`~id`: '1'})
                       CALL neptune.algo.vectors.remove(n)
                       YIELD node, success
                       RETURN node, success" \

Midnight is called 24:00 and is used to mean the end of the day and 00:00 is used to mean the beginning of the day. For example\\, you would say \"Tuesday at 24:00\" and \"Wednesday at 00:00\" to mean exactly the same time."
