Therefore all the information here will have both terms

AND refines our results by requiring that all results have both Stan Lee OR Stanley Martin Lieber as well as Marvel

Searching with OR increases our results, so searching for Stan Lee OR Stanley Martin Lieber brings us this.

NOT eliminates anything that is tagged X-Men.

This leaves us with only information tagged Stan Lee OR Stanley Martin Lieber AND Marvel but NOT X-Men. Which will better enable us to find the information we need.

This is the information tagged

Stanley Martin Lieber

This is the information tagged Stan Lee

There is a lot of information out in the world. How do you find the information you want?

Suppose we need to find information about Stan Lee's work for Marvel's projects besides X-men.

Let's do a search for

Stan Lee

Boolean operators are ways of refining your search to get the best possible results for your subject.

There are three operators:

OR

AND

NOT

This is the information tagged Marvel

This is the information tagged

Stanley Martin Lieber

Currently we have all of Stan Lee's work with Marvel. We only want the work that does not have to do with X-Men.

So we edit our search again, this time adding the Boolean operator NOT

This is the information tagged Stan Lee

So our search becomes

(Stan Lee OR Stanley Martin Lieber) AND Marvel NOT X-Men

This is the information tagged

Stanley Martin Lieber

This is the information tagged Stan Lee

This overlap is the area that is tagged both

Stan Lee OR Stanley Martin Lieber AND Marvel

This is the information tagged Marvel

Now we want the information on Stan Lee concerning his work with Marvel.

So our search becomes

(Stan Lee OR Stanley Martin Lieber) AND Marvel

This is the area that is tagged both

Stan Lee OR Stanley Martin Lieber AND Marvel

but NOT X-Men

NOT removes all the information tagged X-Men no matter what else it is tagged.

But it may not be not all the information on Stan Lee.

Stan Lee is a pen name. Let's add his real name: Stanley Martin Lieber.

So our search becomes

Stan Lee OR Stanley Martin Lieber

There is a lot of information tagged Stan Lee

Searching for Stan Lee brings us this

This is the information tagged X-Men

So let's go over that again
