Searching for files
  The Go To > Resource action in the Navigate menu allows you to quickly find a resource in the
  Workbench by searching resource names.
  You can also do more complex searches for files in the Workbench. For example, to find all files that end with
  .xml:
  
    - On the main toolbar, click the  Search button Search button . .
- Go to File Search tab.
- Type *.xmlinto the File name patterns field and leave the Containing text field
    empty.
 (You can use the pull-down list to select*.xmlif it had been previously entered.)
- Finish entering your search options, for example to scope the search to specified working sets, and click
    Search.
- The Search view displays the results of your search. Right-click on any item in the Search view to open a
    pop-up menu that allows you to remove items from the list, copy search results to the clipboard, or rerun the
    search. To open one of the listed files, double-click it or select Open from its pop-up menu.
If you close the Search view, you can return to it later by selecting 
   Window > Show View > Other...
  > General > Search.
