Used to indicate a word is part of the index. Only used at the end of the book in the index section.

How it works

Add $I before each item in the index. Add hidden terms in {{curly brackets}} to search more words.

$ Index

$I Massalia
$I Money used in Ancient Rome
$I Neapolis
$I Novo Homus

The use of $I before a word or phrase tags the text as an index item. The book reader then uses the text string to search the book for matches.

This means authors and publishers only need to compile the index words themselves, not their location in the text of the book.

Each index word becomes a clickable link once tagged like this.

Extending the range of index words

You can add hidden search terms to the index word. These are invisible to the reader but used to broaden the search.

$I Massalia {{Marseille}} {{Marseilles}} {{Massilia}}
$I Money in Ancient Rome {{Aureus}} {{Solidus}} {{Denarius}} {{Tremissis}} {{Antonianus}} {{Siliqua}} {{Sestertius}} {{Follis}} {{Dupondius}}
$I Neapolis {{Naples}} {{Napoli}}
$I Novo Homus {{New man}} {{Self-made men}}

This is a handy trick to ensure the reader only sees one, human-friendly term (e.g. Money in Ancient Rome), but the software can widen the search to find more useful content. The software will search using the index word or phrase plus anything in the square brackets.
