This is an implementation detail.  I have added a "map fields" and 
language to ParsedObject.  The "handler" can parse metdata into Title, 
Description, Language, or a field.  For the Lucene implementation,  the 
fields will be added to the index are will be searchable by adding the 
field name to the queryString, see below.
       queryString = "+jetspeed +rss +myField:value1" would search for 
"jetspeed" and "rss" in the content and "value1" in the field "myField"

The actual number of search indexes can be hidden in the SearchService.

+1 on supporting many SearchServices.  A search service the search the 
portlet registry has been an implementation that I have always wanted.
