This one is especially for the lazy people like me.
Imagine your friend is unable to search for a topic on Google (due to keyword mismatches!) then you can send him a link and show how to Google for a particular topic.
If you want to see an example click this link
If you want to show your friend how to search for a topic go to LMGTFY
Enter your query, you will get a link to share it with your friend. That's all.
Happy Googling :)
