Hi Netdragon! Carol at Trulia here. When you are searching Smyrna, start using the List view instead of the map view. Under Location you can choose a search radius by miles or commute time. This will expand the area you are searching. You can also zoom in on the map to view more listing bubbles in the area you choose. For example, when I search Smyrna, it shows over 1800 For Sale in the lower right corner but 1800 listing bubbles will not fit on the map. You have to zoom into the location in which you want to check listings.
If you have additional questions, please contact us at http://www.trulia.com/help/ask/
