--------------------------------------
Type: Technical
Reported by: Neil Jenkins <[email-masked]>

Section: 5.5

Original Text
-------------
   o  position: "UnsignedInt"

      The zero-based index of the first result in the "ids" array within
      the complete list of query results.

Corrected Text
--------------
   o  position: "UnsignedInt"

      The zero-based index of the first result in the "ids" array within
      the complete list of query results.  If the "ids" array is empty,
      the value is undefined and MUST NOT be used by the client.

Notes
-----
The position response argument in "/query" is only defined when there is at least one id returned in the response. Make it clearer that when there are no ids returned, the client cannot rely on it being any particular value.
