"No Web pages found that match your query."

I don't know how and why it happen..

It's pretty common (according to me) to see url's popping in and out of the index.
Wait another day or two and see if your page still doesn't appear. Also try pressing F5 a few times(in windows) and see if it appears. It might also been that they weren't able to reach that page under spidering, if so it will probably be in the next update.
