You posted in the Adobe Acrobat Reader forum. You can't create Indexes with Reader, so I moved this to to Acrobat General Troubleshooting.
It's been well over a decade since I've created an Index in Acrobat, so maybe someone else will jump in.
The purpose of an Index (these days) is to make a Search faster. Bookmarks can be included in the Search.
What is not working?
You have taken me a step further... thank you!! I was missing the options in the dialog box that the .pdx provides. So, I am now successful searching and finding the 5 documents in a particular file folder -- and the bookmarks are included. Half-way home!
So this works as long as all users have Adobe Pro DC. If others launch my pdf is just plain 'ole Acrobat (like what comes on computers for free) and I do a search, the results are not found. Do you have a miracle in your other pocket?
Betty, read the link I sent from the Help file. It's supposed to include the Bookmarks.
Are you including the catalog on the CD as instructed in the Help file?
I have read that help page no less than 20 times, and still could not peel back the layers sufficiently! Thank you for pointing out the tree I missed in the forest! The index, of COURSE!
All is well, and with careful attention my documents now have a functional index (well, at least 5 of them are!)
Thank you so much, jane-e for your help... I sometimes get so focus on what doesn't work, I forget to see what does!
Oh, good news! So it is all working as expected now?
So glad to have helped, and it was good for me to refresh myself on Acrobat Indexes. They used to be required—and back then I knew them well—but that was many years ago.
