How to PL/SQL Function returns type

Question

Hello,
I need to create a function, which is returning a list of ID's, which is stored in a type T_IDs, something like:
function search(searchstring in varchar2) return T_IDs
I have a little problem with filling the type inside the function body using a select statement like
select id from table where text like searchstring;
which is selecting a list of ids matching the where-clause. Is it possible to use select into or should I go for another mechanism?
Thanks for any ideas.

Yes, no problem, this is the code I am testing on
create table texttabelle(
id          number(10),
dokument    clob

create sequence seq_texttabelle

insert into texttabelle values (seq_texttabelle.nextval, 'A-Partei gewinnt Wahl in Hansestadt');
insert into texttabelle values (seq_texttabelle.nextval, 'Terror in Nahost: Kriminalität steigt immer weiter an');
insert into texttabelle values (seq_texttabelle.nextval, 'Wirtschaft: Erneuter Gewinnzuwachs in diesem Jahr');
insert into texttabelle values (seq_texttabelle.nextval, 'Olympia rückt näher: Der Fackellauf ist in vollem Gange');
insert into texttabelle values (seq_texttabelle.nextval, 'Wer wird US-Präsident? Obama und Clinton machen Wahlkampf');
insert into texttabelle values (seq_texttabelle.nextval, 'Papst bestürzt über jüngsten Skandal!');
insert into texttabelle values (seq_texttabelle.nextval, 'Wahlkampf in den USA geht weiter:  Clinton und Obama LIVE zu sehen');

create index idx_text on texttabelle (dokument)
indextype is ctxsys.context

CREATE OR REPLACE type T1 as object (
numero number(2)
+);+

The desired function has following specification:
CREATE OR REPLACE FUNCTION fkt_search (search_str IN VARCHAR2) RETURN T1;
The select statement I would like to use is:
SELECT id
FROM texttabelle
WHERE contains (dokument, search_str) > 0;
As I said, I cannot construct the correct select into - statement to fill the T1 with the result ID's from above.
ThanksYour problem is that you are returning a single object from your function, not a collection of them.
