End users don’t have to figure out how to tell Reader to use the index during Finds and Searches, since Reader 8 and Acrobat 8 automatically use it if it’s embedded. idx files generated for each PDF’s index, or make sure that they always travel with the file. Once they’re embedded, you no longer have to keep track of the separate. And I suppose you could use Catalog to create an index of a single PDF too, though I never bothered.Īll that is still possible in Acrobat Pro 8, and the old ways of associating an index with a particular PDF still work.īut here’s Acrobat Pro 8’s new twist: Indexes are embeddable in a PDF. PDF content providers typically index a folder full of PDFs so that a single Search (Command/Control-Shift-F) can hunt down the search text in a whole collection of PDFs. The Catalog feature has been in Acrobat for several versions. We’ve been able to create indexes in Acrobat Pro for many versions now using the Catalog feature (Advanced> Document Processing> Full Text Index with Catalog) (Figure 1).įigure 1. And, since the index knows which page numbers words appear on, the end result is the same. Since the index file is much smaller, operations are lightning-quick. Then when you Find or Search, Acrobat or Reader searches the index, not the PDF. Using Acrobat Pro, you can create a full-text index of the contents of a single PDF and (new to version 8) embed it into the PDF. The little read-out says, "Searching 342 of 575… 343 of 575… 344… 345… 346…" Two minutes later and you’re still staring at the page progression, hypnotized, waiting for a hit: "517 of 575… 518… 519… 520…"īy choosing one little command in Acrobat Pro version 8, you can put an end to this misery and instantly find things in even in the most massive of PDFs. Acrobat (or Adobe Reader, doesn’t matter) finds the first couple of instances in a reasonable amount of time, but soon it slows to a crawl as it hits a dry patch. Your Google-ized instincts immediately reach for the Find (Command/Control-F) field to enter the word or phrase you’re looking for. Text in searchable PDF documents can be selected, copied, and tagged.Based on an article originally published in the DesignGeek e-zine.ĭoes this sound familiar? You open a huge PDF with no bookmarks and no linked TOC, and you need to quickly find the page containing the topic you’re interested in.
