Those who knows and use QAS, Any idea why it search so quick. It gives result of postal address in just a matter of split seconds. I'm wonder how they do it.
I'm actually trying to make the same software, however I can't figure out as to how to make it as fast as the Experian QAS.
I've indexed columns of my database, it gives result in 3 - 5 seconds while Experian QAS gives result in less the a second.
