docs: Obtain a {@link NodeSequence} that returns all (queryable) nodes in the workspace, where each node is assigned the given
  score.
  
  @param score the score for each node
  @param nodeCount the number of nodes (or an estimate) that will be returned
  @return the sequence of nodes; never null
