I can see Advanced Search has an option to select the search order, which works fine. Is there a feature planned wherein users can with a single click rearrange search results, rather than to have research after waiting 90 seconds?
Forum has limits on a member rank and activity point. I am not sure 90 waiting seconds here means that you can not search in shorter waiting time than that.
waittime = 360;
if(activity >= 15)
waittime = (int)(90 - activity);
if(activity >= 60)
waittime=(int)(34.7586 - (0.0793103 * activity));
if(activity >= 100)
waittime = max((int)(14-(activity/50)), 4);
I am unsure I understand your issue correctly. At your activity point, I believe waiting time can be 360 seconds, for posting and can be the same for searching.
