docs: Queries the DHT for its best value related to given key.
  
          There may be several different values for a given key stored in the
          DHT; in this context *best* means the record that is most desirable.
          There is no one metric for *best*: it depends entirely on the key type.
          For IPNS, *best* is the record that is both valid and has the highest
          sequence number (freshest). Different key types may specify other rules
          for they consider to be the *best*.
  
          Parameters
          ----------
          key : str
              One or more keys whose values should be looked up
  
          Returns
          -------
              str
