The results of a search are displayed in the main area of the tool, grouped by file. The file name, the number of matches in that file and the directory are shown. Select a file and expand it to see the line number and text of each line of that file that matches. You can configure the tool to expand the items as they are added as shown in Display.
When there are no matches to display, the Search Files tool displays a message which mentions the number of files searched.
Double-click on the filename to open an Editor tool showing that file and show the first match in that file. Similarly, double-click on the line number to show that line in the Editor. Items that have been edited are shown with a different icon. You can change an item to show as edited or not edited using the Mark Edited and Mark Not Edited commands on the context menu.
You can arrange for an Editor tool to immediately display one of the search matches when you select it. To do this, choose Link to Editor from the context menu in the main area of the Search Files tool. To remove the link, choose Link to Editor from the context menu again.
Use the Filter area to restrict the displayed results by a plain string match or a regular expression match, as described in Filtering information.
