The search field works with the character / paragraph style popups to form a logical AND. Clear the search field to search for any text marked with a style sheet. Set the character popup to none to search for text.
The Whole Words check box makes the script look for whole words. For example, if you search for 'any' as a whole word, QuickIndex disregards 'many'.
