How does Google exact ("") search work so fast?

It finds exact sentence or a phrase among literally petabytes of indexed text, how is this technically possible, even with supercomputers and fastest flashdrives it seems unreal.

Update:

*in fraction of a second

Update 2:

"It's searching a database, not the texts themselves"

What, text IS the database. It finds EXACT QUOTES, hallo.

Update 3:

parallel databases makes sense, that is, if they divide that huge amount of data into databases each few gigabytes size and use separate supercomputers to search it's own "chunk", then the one of thousands of supercomputers will locate that specific quote in fraction of the second and return the result.

    Google is watching you.

    Even before you typed your search keywords, google has already profiled you based on your previous searches and sites you've already visited so they have already "prepared" the results for your quick convenience.

    Hint: It's all in the cookies.

      Untrue, i can now give you an exact quote unrelated to your previous searches and it will return the result in fraction of the second.

    It's searching a database, not the texts themselves. In other words, it searches the index.
