title: Query Redis geospatial data with a bounding box?
body: <p><strong>I am trying to find a way to query geospatial data in Redis with a Bounding Box.</strong></p>
  
  <p>After going through all the documentation on Redis's site the only reference to a bounding box I can find is in the <a href="https://redis.io/commands/georadius" rel="nofollow noreferrer">GEORADIUS</a> command's documentation;</p>
  
  <blockquote>
    <p>Time complexity: O(N+log(M)) where N is the number of elements inside the bounding box of the circular area delimited by center and radius and M is the number of items inside the index.</p>
  </blockquote>
  
  <p>In other words, it seems like there is already a fundamental bounding box inside Redis, but for some reason it does not appear to be readily available to the user. I find this strange.</p>
  
  <p>I am aware that there are some libraries available, such as <a href="https://github.com/RedisLabs/geo.lua" rel="nofollow noreferrer">geo.lua</a> which increases the capabilities of Redis. I would like to avoid extensions to my Redis database if possible, specially since it appears that the concept of a bounding box is already in the geospatial system for Redis. </p>
  
  <p>I keep seeing references to a bounding box everywhere (eg. <a href="http://download.redis.io/redis-stable/00-RELEASENOTES" rel="nofollow noreferrer">Redis release notes</a>) Am I missing something obvious? </p>
