<i>Time complexity: O(log(N))+O(M) with N being the number of elements in the sorted set and M the number of elements returned by the command, so if M is constant (for instance you always ask for the first ten elements with LIMIT) you can consider it O(log(N))</i><blockquote>Return the all the elements in the sorted set at key with a score between_min_ and <i>max</i> (including elements with score equal to min or max).</blockquote>
|
||
|
|
<blockquote>The elements having the same score are returned sorted lexicographically asASCII strings (this follows from a property of Redis sorted sets and does notinvolve further computation).</blockquote>
|
||
|
|
<blockquote>Using the optional LIMIT it's possible to get only a range of the matchingelements in an SQL-alike way. Note that if <i>offset</i> is large the commandsneeds to traverse the list for <i>offset</i> elements and this adds up to theO(M) figure.</blockquote>
