Can't index bfile field

Question

I have a file /tmp/SEA1.txt in my server that contains;
SEA1 COVERA ALL BB02 200101 17024.00
SEA1 COVERA ALL BB03 200101 12614.00
SEA1 COVERA ALL BB04 200101 15204.00
I performed flollow procedures in SQL*PLUS:
CREATE OR REPLACE DIRECTORY TMP_DIR AS '/tmp';
CREATE TABLE "BFILE_TEST"("BFILE_ID" NUMBER NOT NULL, "TEXT" BFILE, PRIMARY KEY("BFILE_ID"));
INSERT INTO "BFILE_TEST" VALUES(1, BFILENAME('TMP_DIR', 'SEA1.txt'));
set serveroutput on
run follow PL/SQL to read bfile:
declare
Lob_loc BFILE;
Buffer RAW(255);
Amount BINARY_INTEGER := 255;
Position INTEGER := 1;
BEGIN
/* Select the LOB: */
SELECT text INTO Lob_loc
FROM bfile_test WHERE BFILE_ID = 1;
/* Opening the BFILE: */
DBMS_LOB.FILEOPEN (Lob_loc, DBMS_LOB.LOB_READONLY);
LOOP
DBMS_LOB.READ (Lob_loc, Amount, Position, Buffer);
/* Display the buffer contents: */
DBMS_OUTPUT.PUT_LINE(utl_raw.cast_to_varchar2(Buffer));
Position := Position + Amount;
END LOOP;
/* Closing the BFILE: */
DBMS_LOB.FILECLOSE (Lob_loc);
EXCEPTION
WHEN NO_DATA_FOUND THEN
DBMS_OUTPUT.PUT_LINE('End of data');
END;
I got:
SEA1 COVERA ALL BB02 200101 17024.00
SEA1 COVERA ALL BB03 200101 12614.00
SEA1 COVERA ALL BB04 20010
1 15204.00
drop index bfile_index;
create index bfile_index on bfile_test(text) indextype is ctxsys.context;
select score(1) title from bfile_test where contains(text,'SEA_',1)>0;
I got:
no rows selected
I should get:
TITLE
100
Question:
Why did I get 'no rows selected'?
I did check the DR$BFILE_INDEX$I table. It is empty. Should it be?
The CTX_INDEX_ERRORS says
AAAZVxAAXAAAAmqAAA DRG-50857: oracle error in drstldef
Any idae what I did wrong?
By the way, I am running ORACLE 8.1.7, OS is LINUX.
Any info is great appreciated.

Anytime you index bfiles, READ on all directories used must be granted to CTXSYS.
