How to optimize ur search in google search engine ?

Hii frds , it is very easy to optimize ur search on google. Means when u search for somethig on goolge it give tooooooo manyyyy results for it and u must be totally confused that what to do ? And which site to prefer ? So for this u can do the following techniques for searching anything on google :-

For searching some word(eg : college) on URL , u can type :- inurl:college

then it will give only those results which have college in it's URL.

Similarly is for finding some word on Text, Title , u can type :- intitle:college , or , intext:college

then it will give all results for website which is having college in it's text or Title.....

If u wanna fing the file of specific format like PDF , then u can simply write on google search engine :-college filetype:PDF

then it will give PDF files in which title college is written.....

ENJOY.....
