There are practically (and probably theoretically) an infinite number of
possible organic molecules. Due to the combinations of possible reactions
from these molecules, there is surely a much higher order of infinity of
reactions to be explored. Without some way of filtering such a database,
you would be guaranteed of starting with so much data that your computer
would never be able to arrive at an answer.
