PDF indexing of Word.doc Keywords: kind of disappointing

Question

If we could embed document properties like Keywords in Word, and then convert Word.docs to PDFs , and then index the PDFs using Acrobat Pro, theoretically it would allow for lightning-fast keyword search and review, through a zillion PDFs.
Except, there are unexpected glitches that are either undocumented... or, if the documentation exists, it's either hard to find or too scantily worded.
Here's a few things I've observed, using Windows XP, Office 2007 and Acrobat 8 Pro:
1. Word document properties only transfer over to PDF if you use the Acrobat tab in Word's ribbon to generate the PDF via PDFMaker, which apparently invokes some 'more robust' implementation of Distiller, than occurs if you simply use the print dialog to print to PDF.  THIS IS PROBABLY A BIG SOURCE OF USER CONFUSION THAT DISCOURAGES MANY USERS FROM GOING ANY FURTHER WITH EXPERIMENTING WITH PDF INDEXING OF WORD DOCUMENT PROPERTIES.  IT CAN LEAD YOU TO CONCLUDE THAT NONE OF THE WORD DOCUMENT PROPERTIES EXCEPT FOR TITLE, CAN SURVIVE A PDF CONVERSION.
2. When you invoke PDFMaker, when the "Save Adobe PDF File As" dialog appears, you must click on the button at the bottom that is labeled "Adobe PDF conversion Options' and verify that the "Convert document information" check box is checked. (This may be able to be set as a permanent user preference somewhere, but I'm not quite sure where.)
3. The Properties fields in Word that will come over, include Title, Author, Subject, and Keywords.  (The Comments field is ignored, as far as I can tell.)
4. You can now index the PDFs, and these Properties fields will also be indexed.....well, Sort Of.
5. "Sort Of", because if you then search for any of the text in your Properties fields, (like for example you search for a word or phrase that you've embedded in their Keywords fields), the advanced search result won't be displayed quite the way 'found hits' normally display in a PDF index search results screen.   You may expect to see the contents of those Keywords fields, show up in the search results in a long list of 'found' file icons with ALL (or a generous selection) of their surrounding Keywords also displayed, and with the specified found keyword highlighted in BOLD.
But, that's not what happens. What you really get is an icon showing the contents of the Title field (which you didn't search for.) It basically means that Acrobat has found a document with something you searched for, in it....but Acrobat is not going to show it to you as easily as you are accustomed to seeing it. You only have two choices: (1) either hover your mouse over each found file's Title icon, one by one, until its screentip-type popup window appears, showing you all the contents of all four of that document's Properties fields; or (2) click on the icon, display the PDF, go to File Properties, and observe that file's properties dialog box.
This is disappointing: the fast, easy, contextual lookup advantages you've enjoyed with regular PDF index searches appear to be unavailable when it comes to viewing search results on indexed document properties. I can understand the logic; (why show other keywords surrounding the searched-for keyword? If they're not in a sentence, there's really no contextual relationship, and therefore no reason to show them.)
However, what if users wanted to store logically related keywords in a deliberate organized pattern..ie,
Texas, Car, 1999, Ford, Mustang, Green
Texas, Car, 2000, Ford, Mustang, White
Texas, Car, 2000, Ford, Mustang, Yellow
Texas, Car, 2000, Chevrolet, Corvette, Blue
Ohio, Car, 2006, Honda, Civic, Silver
...etc.
In this context, all keywords are logically related; it could be a big advantage to be able to use PDF Index search to instantly find and view a list of all 5,328 White 2000 Ford Mustangs located in Texas....then pop up their insurance.doc PDFs for further details.
Allowing the user to set a preference to 'show all stored propery values in the search results' instead of an arbitrary length string of surrounding values, could also be very helpful, so that the full information depicted in the above example could actually be fully displayed, not arbitrarily truncated.
I guess the only workaround is to forget Word's Document Properties, and just embed keywords within the document itself, such as maybe at the end of the document, maybe colored white (so they can't be easily seen).  Formatting them as hidden text doesn't work; Acrobat ignores hidden text when you convert from Word to PDF.

Answer 1

I seem to get hard returns in all cases. That is why I had the short answer. I do not remember if saving as a DOC got rid of the hard returns. Of course the simplest way to find out is to try it. I went to another machine and the Save As to a DOC file did not put in the hard returns (cut and paste did). I should note that the PDF was produced from a totally different word processor and was not a WORD native document. That would suggest it is not dependent on the tags that can be included by WORD and PDF Maker.
