TooltipExchange is a full item info database addon with advanced search capabilities.

It differs from LootLink and ItemSync mainly in that it has a built-in communication module to allow searching other people's item databases as well as your own. TooltipExchange also features Memos, user created item lists that can be used as wish lists, boss drop lists, etc. and can be set to Public to allow your Memos to be browsed by other TooltipExchange users. Items which are found on remote clients are transfered over communication channel and their tooltips are reconstructed locally, allowing browsing of never seen before items.

Features

Searches are performed globally on current communication channel.
Searching by: item name, rarity, equip location, stat (like crit%, AP, resistance etc).

Notes

Item database is empty by default. To populate it with items from your client's local cache use "Database -> Mine Cache" option.

This addon is not designed for low memory usage. As all searches are sent to every client using it, its main optimizations are for fast searching. Also, storing the complete text of item tooltips requires significant, but static, memory consumption.

Recipes aren't stored in database, yet the ones in local item cache are now fully browsable.

Item set details such as the names of items in the set, and set bonuses, are not stored in the database.
