Bash and shell script if statement to do something if a file is found

I have created a shell script to find a string within a text file, then display the results to the screen sorted through grep.

How could I surround this in an if statement so that if results are found then echo "Found!" and display the results afterwards else say "not found"?

I have gotten this far already by using various websites but I am stuck with this.

Here is what I have so far:

echo "enter name "
read search

echo "The String searched for "
grep -i $search $fileName

if [$search ????]
then
echo "Found!"

else
echo "Not Found!" 

fi

Check if grep returns a non-zero length string:

if [ -n "$(grep -i "$search" "$fileName")" ]; then
    echo "Found!"
else
    echo "Not Found!"

Your grep call can be a part of the if statement:

if grep -q "$search" "$filename"; then
  echo "Found!"
else
  echo "Not Found!"
fi
