Searchable PDF files keep the original scanned image for viewing, as well as OCR text in a hidden layer that can be used to full-text search the document or highlight text for copy and paste operations.
Full OCR conversions to PDF that don't include the original image will never preserve the original formatting 100%, especially if there are a lot of images or complex document layout.
Searchable PDF avoids this by keeping an image for viewing along with the text.
These are also known as Image+Text PDF files.
