In this example, you are searching for people who know C programming and have a degree in either mathematics or computer science. To locate that group of people, enter these search criteria in the order listed:

C programming

AND

Degree in computer science

OR

To locate the people who meet the search criteria, the system completes these steps:

1. Locates the people who know C programming. (For demonstration purposes, call this group of people group A.)

2. Searches group A for people who have degrees in computer science. (Call these people group B.)

3. Searches group A for people who have degrees in mathematics. (Call these people group C.)

   The result of the search is the total of the people in groups B and C.
