Maximum document-size of text-search?

Hi.
I'm trying to index the contents of word-documents, extracted text, 
which leads to quite large documents sometimes. This resutls in the 
following Exception:
Caused by: org.postgresql.util.PSQLException: ERROR: index row requires 
10376 bytes, maximum size is 8191

I have the following schema:
andreak=# \d origo_search_index
                                        Table "public.origo_search_index"
           Column          |       Type        
|                            Modifiers
--------------------------+-------------------+-----------------------------------------------------------------
  id                       | integer           | not null default 
nextval('origo_search_index_id_seq'::regclass)
  entity_id                | integer           | not null
  entity_type              | character varying | not null
  field                    | character varying | not null
  search_value             | character varying | not null
  textsearchable_index_col | tsvector          |

     "origo_search_index_fts_idx" gin (textsearchable_index_col)

Triggers:
     update_search_index_tsvector_t BEFORE INSERT OR UPDATE ON 
origo_search_index FOR EACH ROW EXECUTE PROCEDURE 
tsvector_update_trigger('textsearchable_index_col', 
'pg_catalog.english', 'search_value')

I store all the text extracted from the documents in "search_value" and 
have the built-in trigger tsvector_update_trigger update the 
tsvector-column.

Any hints on how to get around this issue to allow indexing large 
documents? I don't see how "only index the first N bytes of the 
document" would be of interest to anyone...

BTW: I'm using PG-9.0beta3
