The limitations of 'image search'

I'm currently attempting to Google the identity of some sort of four-legged critter I keep seeing from the train. So far, 'India animal looks like a cross between deer and camel,' 'Indian gazelle,' 'Indian deer,' and, least likely of all, 'Indian wild camel' have been completely useless.

Should I mention that they seem to have unusually large heads? They seem to have unusually large heads. Also, they primarily come out at dawn or dusk, in the fog. And only near trains that are moving exceptionally fast. Also, one time, a terrifyingly fast bus. But I'm pretty sure it looked a little like a deer, a little like a camel, and a little like a cow.

Somebody told me there's a deer called a blue cow. This wasn't remotely blue, but ...

... jackpot.

According to my search results, which I have not bothered to read, they come in blue and brown. Nilgai it is.

I don't see why my original search didn't work. How come no one else in the world has noticed that these things look like a cross between a deer and a camel?

Wish I'd seen a blue one.

I have nothing to say to you about writing, because I haven't been doing any. However, if you are planning to become fabulously wealthy writing a best-selling novel but can't quite seem to get started, read this old Dave Barry column on the Da Vinci Code.

If you are not hoping to publish a bestseller, read it anyway. 

If you can't read, get someone to read it to you.
