In the Library inspector, select the item you want to search.

To search across the entire library, select Photos. The main window switches to Photos view, displaying all of the photos in the Aperture library. In Photos view, you can use the Browser and Viewer to locate, sort, and adjust photos as necessary.

Make sure the Browser is showing by doing one of the following:

• To show the Browser by itself: Choose View > Browser.

• To show the Browser and Viewer together: Choose View > Split View.

Click the Filter HUD button beside the search field in the Browser (or press Command-F).

In the Filter HUD, choose search criteria or rules from the Add Rule pop-up menu.

When you choose an item from the Add Rule pop-up menu, additional controls become available in the Filter HUD. The Add Rule pop-up menu contains the following items:

• Adjustments: Search for photos based on the type of adjustment that has been applied to them in Aperture, as well as which RAW decoding version was used to render the image. You can also search for photos that do not have a specific type of adjustment applied to them.

• Aperture Metadata: Search for photos with Aperture-specific metadata applied to them, such as version name and project name.

• Attachment: Search for photos based on whether they have audio attachments.

• Calendar: Search for photos by the date they were taken as registered in the EXIF data.You can select a date or several dates in the calendar to search for photos taken on those dates, as well as specify a range of dates. In addition, you can search for photos taken outside of a range of dates. Use the Calendar navigation buttons to navigate through the monthly calendars. Shift-click to select a range of continuous dates; Command-click to select multiple noncontinuous dates.

• Color Label: Search for photos that have color labels assigned to them. You can search for more than one color label at a time. You can also search for photos that do not have a specific color label assigned to them.

• Date: Search for photos based on their creation date. Images that you import from sources other than digital cameras and card readers, such as JPEG or TIFF files, may not have EXIF information associated with them. However, they typically have a creation date assigned to the file. You can use this creation date to locate images using the Date search options.

• EXIF: Search for photos using any EXIF information recorded by the camera.

• Face: Search for photos based on the faces that have been assigned names. You can search for photos that only contain a single named face, as well as photos that have multiple people in them, including the face you’re looking for.

• File Status: Search for photos based on whether they are managed images, referenced images, or online or offline images. You can use the File Status search category to show the photos whose originals Aperture considers missing.

• File Type: Search for files of a specific type, such as RAW or video. You can also search for RAW + JPEG image pairs, movie and audio file attachments, and images edited with external applications.

• Flagged: Search for photos that you have flagged in Aperture.

• Import Session: Search for photos that were imported at a specific time or on a specific date. Aperture keeps track of your import sessions and can identify photos that were imported at the same time. You can also search for photos that were not imported during a specific import session or range of sessions.

• IPTC: Search for photos based on any IPTC information assigned to them.

• Keywords: Search for photos by any of the keywords that you’ve assigned to them. You can select one or more keywords to search for. You can also specify which keywords a photo must have to qualify as a match.

• Photo Usage: Search for photos that have been employed for a specific purpose in Aperture, such as photos currently used in a book, emailed photos, and prints ordered via the Apple print service.

• Place: Search for photos by the location information assigned to them. If you have photos that were shot with a GPS-enabled digital camera or if you’ve identified where photos were shot using Places, you can search for photos by location.

• Rating: Search for photos based on the ratings assigned to them in Aperture.

• Text: Search for photos based on any text associated with a photo. For example, you might search for photos based on text in a photo’s caption or keywords, or in any other text entry. You can also search by multiple text entries.

Do one of the following:

• To specify that a photo must match at least one of the criteria or keywords: Choose Any from the Any/All pop-up menu and “match” from the Match pop-up menu.

• To specify that a photo must match all the criteria and keywords: Choose All from the Any/All pop-up menu and “match” from the Match pop-up menu.

• To specify that a photo must not match any of the criteria and keywords: Choose Any from the Any/All pop-up menu and “do not match” from the Match pop-up menu.

• To specify that a photo must not match all of the criteria and keywords: Choose All from the Any/All pop-up menu and “do not match” from the Match pop-up menu.
