hey all , recently search algorithms got my attention not because its theories  which made the modern web but the algorithms and how it handle millions of records in just a few secounds , all algorithms can handle small amount of data  , but what if we had thousand  or million or even billion then we have to get into algorthims in deepest way to get it faster
i got this link from wikipedia about all known search and data mining algorithms
