GuildBankSearch 

Originally developed by Harros

• Item name, either partial or full.
• Tooltip text below the item's name, partial or full.
• Quality, such as poor, uncommon, and rare.
• Item level, or “iLevel”: The internal stat budget for items. Not to be confused with player level.
• Required level allows you to search for gear available to a given level range. If the upper or lower boundary fields are left blank, those boundaries won't be enforced in the search. That is, with a lower boundary of 35 and no upper boundary, any item usable by level 35s and above will match the search.
• The “Item Category” section allows searching item classifications in the same way as the auction house.
  • Type divides items into the broadest categories, such as weapons, armor, and consumables.
  • Sub-Type classifies items in a given Type even further. The various weapon types such as swords and staves are sub-types of the weapons type, for example.
  • The Slot field allows searching for specific gear slots such as rings or main hands.
