To your answer, i'm not sure what you really asking, but about tricks i can say, google respond to different words in a different way! You can search the same topic but refer it with different key words and you'll receive different results by each search and you'll be connected to more new sources related to the topic each time.
"Please try to write your words more correctly because misspells would make people confuse of what you really asking! However wrong typing happens, i've done a million of wrong typing for my answers, it happens tho! But as far as i learnt, English is not your first language, but however, you can use this site for corrections. It's an online correction site. I just searched and found it now!
