Searcher

A searcher is any card, upon meeting of its effect requirements (assuming the card has any), that is capable of letting you select a specific card(s) from your Deck to Special Summon onto your side of the field, to add to your hand, to place on top of your Deck, to send to the Graveyard or to banish. Your Deck is then shuffled (in the case of placing the card on top of your Deck, the Deck is shuffled before the card is placed on top).

If a game effect instructs a player to retrieve a card from the Graveyard or search for a card in his or her Deck with specific parameters regarding which card that player may select (based on Level, card type, ATK/DEF, and so on), that player is required to reveal the card for which he or she searched to the opponent. If a player searches his or her Deck, he or she must shuffle it afterwards.
