Search results labeled 'This site may harm your computer'

This warning message appears with search results Google have identified as sites that may install malicious software on your computer.

If you click the title of the result, you'll be shown the warning rather than being taken immediately to the webpage in question. You can choose to continue to the site at your own risk.

Fill in the blanks (*)

The *, or wildcard, is a little-known feature that can be very powerful. If you include * within a query, it tells Google to try to treat the star as a placeholder for any unknown term(s) and then find the best matches. For example, the search [ Google * ] will give you results about many of Google's products (go to next page and next page -- we have many products). The query [ Obama voted * on the * bill ] will give you stories about different votes on different bills. Note that the * operator works only on whole words, not parts of words.

Search within a specific website (site:)

Google allows you to specify that your search results must come from a given website. For example, the query [ iraq site:nytimes.com ] will return pages about Iraq but only from nytimes.com. The simpler queries [ iraq nytimes.com ] or [ iraq New York Times ] will usually be just as good, though they might return results from other sites that mention the New York Times. You can also specify a whole class of sites, for example [ iraq site:.gov ] will return results only from a .gov domain and [ iraq site:.iq ] will return results only from Iraqi sites.

Google Phrase search ("")

Phrase search ("")
By putting double quotes around a set of words, you are telling Google to consider the exact words in that exact order without any change. Google already uses the order and the fact that the words are together as a very strong signal and will stray from it only for a good reason, so quotes are usually unnecessary. By insisting on phrase search you might be missing good results accidentally. For example, a search for [ "Alexander Bell" ] (with quotes) will miss the pages that refer to Alexander G. Bell.

Search with boolean operators

The Boolean operator AND, OR, NOT can be added to re-fine your searching result when using Google Search.

AND(+): The AND operator forces Google to match the search results against all your keywords. The operator is signified by a plus sign (+). Place the plus sign immediately before any words without a space, for example: Google +search

NOT(-): The NOT operator excludes words. The symbol is a minus sign (-). Place the symbol immediately before a word.
for example: Google -search

OR: The OR operator is helpful when using obscure keywords that might not return much of value if used singly. It also neatly divides a search along two concurrent avenues of exploration. Simply type OR (use capital letters) before a keyword and leave a space between the operator and the following keyword. Google then accepts matches to the keyword preceding the operator or following the operator.
for example: Google Android Maps OR Earth
