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
Never mind... I was having a btree index on search_value too, which of
course caused the problem.
