Search Target Window
Each time you execute a search, the results are placed in a new Search Results window. In other words if you execute 5 searches then you’ll have 5 Search Results windows open.
To help manage your screen you may not want that many Search Results windows open. You can actually limit the number to one if you desire.
When a Search Results window opens click the Search Target icon (bull’s eye) on its toolbar. With this window open and the icon clicked the next search you execute will erase the existing results and place the new results in their place.
