Why would you save search criteria as a saved search?

What will be an ideal response?

For many searches, you can easily "save" the results—in other words, preserve the
grouping of images that match the search criteria—by creating an album or by tagging
all the photos returned by the search with the same keyword, Place, or Event tag.
Once established, these groupings are static; their content will not change over time
unless you manually add or remove photos or tags. A saved search, on the other hand,
can be more versatile; you can run the same complex search again and again, returning
more images that match the search criteria each time you add photos to your catalog.
