We've almost got UdmSearch up and running, and I'm noticing something odd:

-rw-------  1 pgsql  pgsql   204800 Jan  6 00:05 url
-rw-------  1 pgsql  pgsql  1622016 Jan  6 00:05 word_url

url is:

CREATE TABLE "url" (       "rec_id" int4 DEFAULT nextval('next_url_id') PRIMARY KEY,       "status" int4 NOT NULL
DEFAULT0,       "url" character varying(128) NOT NULL,       "content_type" character varying(32) NOT NULL DEFAULT '',
    "last_modified" character varying(32) NOT NULL DEFAULT '',       "title" character varying(128) NOT NULL DEFAULT
'',      "text" character varying(255) NOT NULL DEFAULT '',       "size" int4 NOT NULL DEFAULT 0,       "indexed" int4
NOTNULL DEFAULT 0,       "last_index_time" datetime NOT NULL DEFAULT 'Thu Dec 31 20:00:00 1970 GMT',
"next_index_time"datetime NOT NULL DEFAULT 'Thu Dec 31 20:00:00 1970 GMT',       "referrer" int4 NOT NULL DEFAULT 0,
  "tag" int4 NOT NULL DEFAULT 0,       "hops" int4 NOT NULL DEFAULT 0,       "keywords" character varying(255) NOT NULL
DEFAULT'',       "description" character varying(100) NOT NULL DEFAULT '',       "crc" character varying(33) NOT NULL
DEFAULT'');
 

and word_url is:

CREATE  INDEX "word_url" on "dict" using btree ( "word" "varchar_ops", "url_id" "int4_ops" );

=============

is it just me, or does an index ~6x the size of the data itself look
"odd"?

Its an older v6.5.0 database (haven't had time to upgrade *sigh*), so if
explains it, so be it...I'll do an upgrade ASAP...but if that doesn't?

Thanks...
