When you search for string, either explicitly by using the Search icon 
,
or implicitly by tapping on a word or name in a Program Description, the
results are displayed in a Results List.
Results are always listed chronologically, and by default, they list only the first unique upcoming showing of every match. If you want to see all duplicate showings (including any in the past), scroll forward until you see the line "Tap here for all shows/times", and tap on it.
From a Results List, you can tap on any Channel Number to jump to a Channel Listing of other programs showing on that channel, starting at the same time. Tap on a Date to jump to the Date/Time page, or tap on a showtime to see a Time Listing of other programs showing at that time. And finally, tap on any program to display Details about it.
You can also tap the Favorites icon 
to add the current search to your list of Favorites. You can even add
some or all of the matching shows as Reminders to
your Calendar.
