In Laserfiche 10 and 11, the Search feature is available within the Recycle Bin, and several criteria can be searched on using the GUI as well as Advanced Search Syntax. 

With the "Date" criteria, I'm able to search based on "Created" or "Last Modified" date, and I can adjust the syntax to be as specific as I want, however I have not found a way to search based on "Date Deleted" (I've tried various different trail-and-error adjustments in the syntax, to no avail). Is it possible to search based on this date?

Additionally, with the "User" critereia, I'm able to search based on "Created By", "Owned By", or "Last Modified By", and I can also adjust the syntax to be as specific as I want there, however I have not found a way to search based on "Deleted By" (I've tried various different trail-and-error adjustments in the syntax, to no avail). Is it possible to search based on this user information?

Both "Deleted By" and "Date Deleted" are pieces of information associated with entries within the Recycle Bin, and are able to be shown in column views alongside the entries, but it appears we're not able to search on that information.

Does anyone know of a way to use this?
