The most common reason to perform a search is to display a selection of images within 
a project. By selecting a project and using the Query HUD, you can quickly display 
specific images, hiding the rest from view. For example, you might isolate and display 
only those images of a certain subject, pose, rating, or location. Your search doesn’t 
change the contents of the project; it only temporarily changes the images you view in 
the Browser. If you cancel the search criteria in the Query HUD, all of your images 
appear in the Browser again. The Query HUD is preset to show images that are unrated 
or better, hiding rejected images. You can change the Query HUD criteria to show 
rejected images if you wish.
You can also create special albums, called Smart Albums, whose contents are derived 
solely by search criteria. For example, you might create a Smart Album that searches for 
and displays all portrait images from the entire Library. When you create a Smart 
Album, you use the Query HUD to define criteria for the images that should appear in 
it. For more information about creating and using Smart Albums, see Chapter 13,

Grouping Images with Smart Albums
Aperture can locate images based on many types of information associated with the 
images. When you import images into Aperture, certain information is automatically 
assigned to each image, including EXIF metadata such as image date, photographer, 
camera technical data, filename, and much more. You can also assign your own 
metadata to images, including keywords, summaries, captions, and information used 
by IPTC fields, and then locate your images by searching for the metadata.
