No, but you will lose all documents you selected to delete. That is why one shouldn't use the SMART FOLDERS in the SEARCH FOR section to delete files. And you may loose some screws too.

You might want to go to Finder > Preferences and uncheck all the "Search" items. Then you won't see those smart folders anymore. Those are not copies of your files. They do not take up space on your hard drive. Ignore them.
