How do I make an output for grep fail?

I am using if-else statement to search for keywords and displaying the results in the terminal, here's an example of my code.

read finding

if ["$finding" != "" ]; then
   grep $finding information.txt
else
   echo "No such information in database."
fi

But the terminal does not display anything if i key in information that does not exist. I started shell about a week back, might need more explanation on how certain code works.
