Access this feature by clicking either on the speed button or the appropriate choice on the Prints/Prices area of the Menu Bar.
Using this feature you can bring up every entry in the database. From this window you can initiate either a Free Text Search or a Boolean Search of the entire database. You cannot have an artist window open to search the universal database, as by definition this is limiting your search. If you wish to search, in either manner, for prints by a particular artist using search criteria, open the artist title window first, then the boolean or free text search windows.
Once the All Entries window is open, you have your choice of searching by Free Text or Boolean. Clicking on either of the appropriate choices brings up a window, detailed in the help file under the Free Text and Boolean sections. The searches work the same regardless of whether you are in the All Entries window or a particular artists window.
