Some Google Trix

Basic

+ and -

The plus forces Goggle to include your entry in the search. Just put it in front of the keyword without space. The same goes for the minus. It does exclude your keyword from the search so that Google doesn't show results containing this keyword

OR

This command returns results which contain at least one of the entered keywords. It is important to write it with capital letters because otherwise Google won't accept it as command.

By adding this in front of a keyword (without space) you ask google to return results which contain a synonym of the word.

This will find also pages containing the "help" or "guide".

*

The asterix is used as placeholder for google and tells that you don't care what word google inserts instead of the asterix. this command is especially usefull in combnation with the other commands.

This would return any executable it could find.

..

You can use two fullstops in order to search within a range of numbers.

Search Engine Optimization

allintitle:, intitle:, allintext:, intext:, allinanchor:, inanchor:, allinurl:, inurl:

Because the discription of these is more or less the same I'll write it one for all of them.
When using a command with "all" in front of it it will search all of the entered words in the asked place. It is important, that this commands can NOT be combined with others.
When using a command without "all", this causes Google to search for the first word after the command in the space and the second word MIGHT be menioned somewhere.

Calculating

Basic operators

You can use all the basic operators like +,-,*,/ etc.

Roots

When you want to have the squareroot of something then use sqrt(x)
If you want to have any other root then simpy type 3th root of x

Logarithms

There are two logarithms that Google knows.

• ln(x) is the natural logarithm (that means with base e)
• log(x) is the logarithm with base 10

Converting

Angles

Google can convert fom radian to degrees and vice versa. Simply use in degrees or degrees in radians.

Quote

90 degrees in radian

Numeral systems

Just write the number you want and then write the system to which you want to convert it to. Works also for roman numerals.

Quote

• 10 in hex
• 54 in roman numerals

Other scale units

You can convert most of the common units by just writing the value you want to convert and then adding "in x" where x is the desired unit.

Quote

• 10 euros in dollars = 10 € in $
• 20'000'000 km in light-second
• 1 teaspoon in oz

I hope this is usefull and that not everyone already knew everything.
