Your drive(s) need to be indexed periodically for Sherlock's "Find by Content" to work properly.
Before you can search the contents of a disk's files, you must create an index of the disk. If you have modified files on the disk since it was last indexed and you want to search the modified content, you need to update the index.
The only way to be sure that find by content will always work is to index your drives each day. You could set up a schedule in Sherlock to index the drives each day at a specified time but that slows down your system while you are trying to use it.
Index & Shutdown tells Sherlock to Index your hard drives and then shut down. You can run it at the end of each day when you are ready to shut down.
