[Go] Index Search difference

An index is an attribute
Retrieval is a behavior

Simple example, a class has 40 men and women, 25 boys, 15 girls.
So in order to quickly find students, we first group students, then the name of this group is the index. We can be divided into boys and girls.
Now for example I tell you xiaoming is a boy, then we will go to the boys group inside to find him. The "find" behavior at this time is search.

As you can see, with the index, we retrieve the information of the requirement more quickly.
