Search for a big varchar2 field that contains specific string

Question

Hi to all,
I've created a table with VARCHAR2 column and size of 4000 and a CONTEXT index for it. I use this SQL statement to search for a field that contains a specific word:
SELECT text_body
FROM my_table
WHERE CONTAINS(text_body,'my_word')>0;
this goes so well in SQL plus, so how can I implement this in my form?
Thanks.

Dear Craig,
I installed forms 10g R2 ,besides I corrected a fault in the LOOP syntax.Thanks, The code now is correct with the function CONTAINS. but when I run my form and push the button, my form takes lots of time and return two errors:
frm-41839 "Disc I/O error on temporary record buffer file%s".
and frm-40900 "Unable to locate record buffer. Clear form to continue".
the second error occurs due to memory low space I think.
Dear Morgan,
You are totally right with the function INSTR, but I use the function CONTAINS as it has large capabilities in my search. I even use CTXCAT index instead of CONTEXT index ,with function CATSEARCH but the problem still exists. All of the previous ways run better in SQL but not in forms(without cursor). Suppose I'm wrong with this technique. Is there another way to make such a search?!
This is the new code:
DECLARE
     CURSOR cc IS
SELECT *
FROM my_table
WHERE CONTAINS(MY_TEXT_FIELD,'first_word AND second_word')>0;
copy_cc my_table%rowtype;
BEGIN
     OPEN cc;
     FETCH cc INTO copy_cc;
          LOOP
          :FORM_TEXT_FIELD:=copy_cc.my_text_field;
     EXIT WHEN cc%notfound;
          NEXT_RECORD;
          END LOOP;
          CLOSE cc;
END;
Regards.
