Here are some google search tips & tricks which we can use to make our search more relevant & powerful.
Search for exact phrase or word
When you type your search like - where can i found good blogs , google split this phrase into each words & ignoring grammar & helping verbs ("are" , "is" , "the" etc..) , then look into there database for these words ("where" , "found" , "good" , "blogs" ) & fetch results according to some algorithms , hence showing relevant search results.
So when you want to search exact phrase without splitting sentence into words you can type your search like this "where i can found good blogs" .
