Words to be swapped must be specified in the list. The Indexation module looks for text lines beginning with the specified words.
If a word is specified in the prefixes list, then the Indexation module looks for text lines in the view pane beginning with that word. Lines containing only the specified word cannot be swapped.
When two or more words are swapped, they must be specified in the prefixes list if you want them to appear in the index.
If the prefixes list contains a repeated word, the Indexation process considers only the longest prefix. For example, when "Township of" and "Township" are in the same list, only "Township of" is used. A word cannot be duplicated in the list.
If the prefixes list is empty, the Swap Prefixes option has no effect.
The prefixes list is not case-sensitive or space-sensitive, but it is aware of accent marks.
