Your description suggests you've only inserted the scanned page images into Word. To get the text, you actually need to run an OCR process on the scanned page images (you can do this with Adobe Acrobat Pro 8 [available as a free download from
http://www.techspot.com/downloads/4683-adobe-acrobat-8-free.html - note the serial# mentioned there], or with the OCR packages that come with many scanners), then insert the text into Word. The inserted text will have all the qualities of normal text in a document. Do note that OCR conversions often require some post-conversion editing to correct OCR errors.
