How to implement advanced search ?

What generic options must have a multi-BTS adavanced search :

  • Search field
  • Specific component/package/software
  • Status : each BTS will be able to set his own differents status
  • Importance : each BTS will be able to set his own different importances
  • Assigned to
  • Reported by
  • Due for a specific release (each BTS must then be able to set his own releases)

Anything else ?
