Hi Cclark,
Great question. Under section 4.3.1.1 of the Help doc here
http://worldmap.harvard.edu/site_media/docs/WorldMap_Help.pdf it describes how at the bottom of the metadata form you can control how attributes in your layer are displayed when clicked on and which fields are searched when using the form at the bottom of the layer list.
Here is what it says:
------------------------------------------------------
For Shapefile datasets an attribute control table is automatically generated with the following columns.
These controls let the user control how attributes are displayed when using the Identify tool and clicking on a feature to return attributes in the right-hand panel:
• Attribute - Lists the fields in the database.
• Display Title - Is used to control how the fields are displayed when a user clicks on the layer on the map and returns attribute information in the panel to the right.
• Display Order - This is the order in which the attribute information is listed when returned in the panel to the right after a click on a map. NOTE: The field which is displayed first is used in the summary table in the upper part of the panel to the right. It is best to designate a field to be first which provides meaningful information at the record level.
• Visible? - This toggle determines whether a given field is displayed at all when one clicks on the map using the Identify tool.
• Searchable? - This toggle determines whether the field will be searchable from the text search box to the lower left of the map.

Best,
