The Platinum Edition of the 7th Edition of Perry's Handbook of Chemical Engineering came on a CD with an Adobe edition with a special Adobe add-on that allowed searching of multiple articles at once. This edition of the famous print book played the individual sections as separate articles, and latter versions of Adobe Reater must open the sections one-by-one, making the search function almost useless.
Is there an add-on that will allow multiple-article searching like that? Where to find it?
No, but it's possible to create an index (with Acrobat) which allows that.
You can't do it if you only have Reader.
With the advanced search of Adobe Reader you search the whole CD.
