Search Functionality on Web Page

[gaw]

The search function on the Visio published web pages is not picking up the displayed shape names.  The displayed names are set to a certain data field associated with the shape. When I published with 07, it worked fine.  With 2010 I have tried both VML and XAML, as well as various verision of IE, but those do not seem to make a difference.  If I re-publish a legacy Visio page with 2010, I have the same search issues. If I use a page published with 07, the search picks up the shape name.  Any thoughts?  Are there configeration changes I can make to 2010 that might address this? Thanks in advance
