Adobe Acrobat Reader Version 3.01 Adobe has created two flavors of Acrobat Reader 3.01, Acrobat Reader and Acrobat Reader with Search. The difference is that Reader with Search is larger because it contains two additional Acrobat plugs-ins (Acrobat Search and AutoIndx) with corresponding support files and documentation. These additions allow the user to search within a collection of PDF files on a hard disk, CD, or local area network for which an index file has been created using the Acrobat Catalog tool (a copy of which is included in Acrobat 3.01 for Windows and Macintosh). They are not needed for searching within PDF files stored on a Web server (this requires a search engine running the Web server). This Reader does not have an expiration date.
