Search limitation by TTH on the Hub. Time during which one search inquiry (in minutes is authorised) is established. It becomes by command !tthsearchperiod <period> in chat. Thus at search attempt on TTH more often, than it is set in adjustment, search inquiries of users without the rights of the operator will be ignored. The plugin has no switch and starts to work at once at inclusion. If wish to disconnect this function, it is simple deactivate this plugin.
