They probably update these answers offline. I tried "how do you profit from options" and got:

> Call Options: You buy these when you believe a stock's price will go up. If the stock rises past your strike price, the option's value increases, allowing you to sell it for a profit or exercise it to buy the stock at a discount.

> Put Options: You buy these when you believe a stock's price will go down. If the stock falls below your strike price, you profit.

Which leaves me wondering if changing the search textually busts some cache that they update using a slower/smarter model.
