I have to index a document containing many words beginning with a special
characters (e.g. greek characters) or numbers in the format "number-word" or
"special character-word". Is there a possibility to say Word to sort these
entries according to the first character of the word after the hyphen, so
that e.g. "5-Hydroxylysin" would appear in the index under the letter "H"?

Many thanks for your suggestions, Pius.
