Advanced searching returns empty array sometimes

[Kow]

Hello,

I've encountered a problem and I'm not sure about the cause. I have
desktop application that enables users to create custom searches based
on various parameters. Sometimes (I can't tell what is the cause) the
API returns an empty array. After a second, retrying it returns a
normal list with many tracks as it normally would.

The query is assembled like this:

'http://api.soundcloud.com/tracks.json?offset=' + offset +
'&filter=public,streamable' +
'&tags=' + options.tab.q_genre +
'&created_at[from]=' + created_at +
'&duration[from]=' + mix_only +
'&order_by=' + options.tab.q_order_by +
'&consumer_key=' + this.consumer_key;

Best regards,
Tibor

Do you need any additional information to help to debug this? Maybe an exact time when a request "failed"?
