About the Search tab
These topics describe the features available if you include a Search tab in your help design.
A compiled help file can include a Search tab that allows a user to search through every word in a help file to find a match. For example, if a user does a full-text search on the word "index," every topic that contains the word "index" will be listed.
Depending on how complex your help system is, the Search tab can contain either basic or advanced full-text search functionality. Advanced full-text search allows a user to search using boolean, wildcard, and nested expressions.
