At this point, you already know how to add an index to a Word document. However, there are a few things we should tell you about this feature.

First of all, the indexes base their content on the titles. Word lets the user organize documents into hierarchies based on titles. Therefore, in the style section, you will see options such as Title, Title 1, Title 2, and so on. You should use these formats to organize your document. Word will then know how to create an index automatically. The application will add each title according to its importance.

Secondly, the indexes must be updated manually. When you add a new section to the file, click on the table of contents and click on Update Table. At that time, the new titles you have added will be displayed in the index.
