How to get exact match when working with Oracle Text?

Question

Hi,
I'm running Oracle9i Database R2.
I would like to know how do I get exact match when working with Oracle Text.
DROP TABLE T_TEST_1;
CREATE TABLE T_TEST_1 (text VARCHAR2(30));
INSERT INTO T_TEST_1 VALUES('Management');
INSERT INTO T_TEST_1 VALUES('Busines Management Practice');
INSERT INTO T_TEST_1 VALUES('Human Resource Management');
COMMIT;
DROP INDEX T_TEST_1;
CREATE INDEX T_TEST_1_IDX ON T_TEST_1(text) INDEXTYPE IS CTXSYS.CONTEXT;
SELECT * FROM T_TEST_1 WHERE CONTAINS(text, 'Management')>0;
The above query will return 3 rows. How do I make Oracle Text to return me only the first row - which is exact match because sometimes my users need to look for exact match term.
Please advise.
Regards,
Jap.

But I would like to utilize the Oracle Text index. Don't know your db version, but if you slightly redefine your index you can achieve this (at least on my 11g instance) :
SQL> create table t_test_1 (text varchar2(30))
  2  /
Table created.
SQL> insert into t_test_1 values ('Management')
  2  /
1 row created.
SQL> insert into t_test_1 values ('Busines Management Practice')
  2  /
1 row created.
SQL> insert into t_test_1 values ('Human Resource Management')
  2  /
1 row created.
SQL>
SQL> create index t_test_1_idx on t_test_1(text) indextype is ctxsys.context filter by text
  2  /
Index created.
SQL> set autotrace on explain
SQL>
SQL> select text, score (1)
  2    from t_test_1
  3   where contains (text, 'Management and sdata(text="Management")', 1) > 0
  4  /
TEXT                             SCORE(1)
Management                              3
Execution Plan
Plan hash value: 4163886076
| Id  | Operation                   | Name         | Rows  | Bytes | Cost (%CPU)| Time     |
|   0 | SELECT STATEMENT            |              |     1 |    29 |     4   (0)| 00:00:01 |
|   1 |  TABLE ACCESS BY INDEX ROWID| T_TEST_1     |     1 |    29 |     4   (0)| 00:00:01 |
|*  2 |   DOMAIN INDEX              | T_TEST_1_IDX |       |       |     4   (0)| 00:00:01 |
Predicate Information (identified by operation id):
   2 - access("CTXSYS"."CONTAINS"("TEXT",'Management and
              sdata(text="Management")',1)>0)
Note
   - dynamic sampling used for this statementJust read that you indeed mentioned your db version in your first post.
Not sure though if above method is already available in 9i ...
