A stop list decreases the size of the full-text search index, which results in a smaller compiled help (.chm) file because fewer words are indexed. This is especially important if you have a large documentation set. All words in the stoplist are omitted from the search. These are usually commonly occurring words or numbers, such as "the," "and," or "1" that a user is unlikely to search for.
When the help editor creates a new help project, it automatically adds a full-text search stop list file stoplist.stp to the project folder. The HTML Help Project (.hhp) file already assumes you will use a stoplist and has the relevant property set in the [OPTIONS] section.
|Do not set the stop list as read-only, it will not function if this property is set|
The default stop list contains English words to be excluded. If you target another language, you will have to change the stoplist content.
You can add a full-text search stop list option to the HTML Help Project (.hhp) file using Notepad or HTML Help Workshop.
