About the Catalog feature

You can define a specific group of PDFs as a catalog and create a unified index for that entire collection of documents. When users search the cataloged PDFs for specific information, the index makes the search process much faster.

When you distribute or publish the collection on a CD or website, you can include the index with the PDFs.

You can catalog documents written in Roman, Chinese, Japanese, or Korean characters. The items you can catalog include the document text, comments, bookmarks, form fields, tags, object and document metadata, attachments, document information, digital signatures, image XIF (extended image file format) metadata, and custom document properties.
