Backward compatibility for the human mind…

Thursday, February 10th, 2011

Don’t worry, its not a post on psychology. Just a whacky title.

Not just systems, but humans (and by extension data) too needs backward compatibility. Case in point the Train numbers have changed from well over a month. But lots of users are still searching for the old numbers:

6604

4646+train+route

2978

6338+ticket+availability

And also, Got one feedback yesterday, which said:
“i asked for rail fare, it gave result for flight…”

search query pertaining to above feedback was:
rail fare of 2433, rajdhani express

What was happening in this case was, since it got a flight with no. 2433. It unwittingly showed the results of the same.

So hey you anonymous friend, who got us to act, thanks! And some good news for you, and also to other users, who must have been suffering in silence. We made a change so you can search like this also, for as long as you like. And when you do get used to the new numbers, that are of course supported as well.
