'Mana' is simply a count of energy you have generated from your permanents. If you tap a forest, you have added one green 'mana' to your 'mana pool', so you can spend that one green mana on a spell or ability.
If a card adds mana to your mana pool, you aren't searching for any card, there is no card 'called' mana, and the card does not mean you get to do anything with 'land' cards from hand or library. All it means is you've now got some extra mana to use that phase, exactly as if you'd tapped some land for it.
