Partitioning the Text Index

Question

Hi,
I need to know the possibility of partitioning the oracle text index which is already been built.
Could anyone post some sample code for that?
Thanks in advance.

I thought there might be a problem with DETAIL_DATASTORE and partitioning, but it seems to work fine for me.
Are your tables range partitioned? See the testcase below, and see if you can modify it to produce the error you're seeing.
drop table pt2;
drop table pt1;
create table pt1 (
  id number   primary key,
  part_key    number,
  dummy       varchar2(1))
partition by range (part_key)
( partition p1 values less than (2),
  partition p2 values less than (maxvalue)
create table pt2 (
  id          number primary key,
  part_key    number,
  fk          number,
  line_number number,
  text        varchar2(80),
  constraint  pt2fkc foreign key (fk) references pt1(id) )
partition by range (part_key)
( partition p1 values less than (2),
  partition p2 values less than (maxvalue)
insert into pt1 values (1, 1, 'x');
insert into pt1 values (2, 2, 'x');
insert into pt2 values (1, 1, 1, 1, 'the quick brown fox ');
insert into pt2 values (2, 1, 1, 2, 'jumps over the lazy dog');
insert into pt2 values (3, 2, 2, 1, 'now is the time for all good men ');
insert into pt2 values (4, 2, 2, 2, 'to come to the aid of the party');
exec ctx_ddl.drop_preference  ('mymd')
exec ctx_ddl.create_preference('mymd', 'DETAIL_DATASTORE')
exec ctx_ddl.set_attribute    ('mymd', 'DETAIL_TABLE', 'PT2')
exec ctx_ddl.set_attribute    ('mymd', 'DETAIL_KEY',   'FK')
exec ctx_ddl.set_attribute    ('mymd', 'DETAIL_TEXT',  'TEXT')
exec ctx_ddl.set_attribute    ('mymd', 'DETAIL_LINENO','LINE_NUMBER')
create index pt_index on pt1 (dummy) indextype is ctxsys.context
parameters ('datastore mymd')
local
/I'm testing on 11.2.0.2. If this testcase gives you an error on an earlier version, it must be a bug that has been fixed.
