Index Fixer is an Acrobat Exchange plug-in which enables Acrobat Search indexes created by Acrobat Catalog to be used with password-protected files (i.e. files with open passwords).
Files with open passwords cannot be indexed with Acrobat Catalog as it does not know what the passwords are, so they must be indexed before being password-protected. Once indexed, a password can then be added, but when a search is performed the search plug-in will detect that the file has changed since the index was built, and will display an error message. Most users get irritated by this pretty quickly and think that there is a problem with the index.
Index Fixer ... THE solution
Index Fixer will fix the index so that Acrobat Search will not think that the protected documents have changed since the index is built, and so no error message will be displayed. Of course, the user will still be prompted for the document's open password, but even that can be removed by use of a custom plug-in (contact us for details).
OK, so you want to stamp your document. Maybe you need to give reviewers some advice about the document's status or sensitivity. This tip from author Ted Padova demonstrates how to add stamps with the Stamp Tool along with related comments.
