Searching for Terms in Zones
Zone searching is useful when you believe that limiting your search to a
particular zone will produce more accurate search results. If you specify a zone like
the document title or a first level heading, you can ensure that your search term
is the primary focus of the document, rather than simply being briefly
mentioned in the body of the text.
IN Operator
If document zones have been defined for the collection you are searching, you
can use the IN operator to search for terms in zones. Your query terms must be
enclosed in parentheses. For example, if you are looking for information on the
Grammy awards, you can issue this query to search for grammy in the title to find pages have the Grammy awards as their primary focus.
