node.js - Use zscan on score -

according https://github.com/noderedis/node_redis/issues/896

i have zset , saving tokens(element) corresponding timestamp(score)

now want delete tokens older particular timestamp using zscan.

redis.zscan('my_key', cursor[i], 'match', '*', "count", count, function(err,    console.log(err);   console.log(reply); }); 

problem having zscan return values irrespective of timestamp.
'match' paramter checks pattern on elements(token). want tokens older particular timestamp(score).

for example :

var startingtime = new date().gettime();       redis.zrangebyscore("iflychat_auth_token", 0, startingtime - 43200000 * 2 * 7, function (error, data) {        // return token older 7 days.         }); 

is there way use 'match' on score

redis.zscan('my_key', cursor[i], 'match', < timestamp, "count", count, function(err,    console.log(err);   console.log(reply); }); 

zscan doesn't have score range option. simplest alternative using redis' zremrangebyscore, possibly so:

redis.zremrangebyscore('my_key','-inf', timestamp, function(error,data) { ... }); 

note: if need exclusive range, i.e. < timestamp, prepend ( when sending value.
