In my experience you are more likely to see the "jump to" link if after you enter the keyword in the search box, you click the adjacent blue magnifying glass icon displayed on the search bar instead of using your "enter" key. Ignore any suggestions in the dropdown list; they may not produce the "jump to." Also be sure you enter the keyword without quotes.
Or you can use the Topic Search method that TT AmyC mentioned above by going to the left menu column to TAX TOOLS>Tools>Topic Search. It provides a list of all topics.
