      we switched from Reader 5 to 7.




The Search engine used in Acrobat 5 is different than the one in Acrobat 6 and later. This is probably the source of the difference.

Usually, adding tags to the PDF will improve the search results. in the case of your PDF file however, the accesibilty report returns the following:

      Accessibility





      The checker found 2 font(s) missing information needed to determine the
      characters that correspond to the symbols (glyphs) in the font.





      The font "FuturaBook" has 31 unrecognizable glyphs out of 31 total glyphs.
      The font "FuturaHeavy" has 13 unrecognizable glyphs out of 13 total glyphs.




So, I suspect the font is malformed beacuse even after adding tags, I'm still not getting any results. Where did you buy the font from?

      although we still can copy and paste text from the PDF document to a text
      editor.




When I do this on the Mac, I get symbol characters instead of the actual text, so I suspect a font encoding problem

Try a different font, like Times, and see if you get the same results.
