Abstract:

In order to make a help system really helpful, you need to provide an effective index. But many online help writers face two dilemmas when it's time to index their help systems: How to prepare a useful index that meets the users' needs and how to code the keywords to make the index compile correctly. This article provides tips to help writers solve both problems.
