Guild Search is a utility to help guild leaders and officers. It allows searching the guild roster, particularly the notes and officer notes. Many guilds will keep meaningful notes in those fields including the the player names for alts. It is very useful to be able to search a large guild roster to find characters. For example, with the recent rise in compromised accounts, if the right information is in the notes, it makes it easy to find all the alts of a player and demote them.

It has options to allow configuring which fields will be searched.

Guild Search displays the following items:

Class-colored character name
Level

Officer Note

Last Online

You can search the following data:

The Last Online column is an approximate based on the data available in the guild roster. It will always be at least an hour off because the smallest unit of time the roster provides is hours.
