Oracle Text Help

Question

Hello Gurus,
I am new to Oracle Text so i need your valuable inputs in resolving an issue i am facing.
Here is the table definition and sample data:
create table test ( a varchar2(100));
insert into test values('Hello How are you');
insert into test values('Just to say you Hello');
insert into test values('I know you');
insert into test values('you know');
insert into test values('you may not know me');
insert into test values('do i know you');
SQL> SELECT * FROM test;
A
Hello How are you
Just to say you Hello
I know you
you know
you may not know me
do i know you
6 rows selected.
If user enters search criteria ('you know', for example); i need to return all the records having 'you' AND 'know' anywhere. Hence for search criteria 'you know', i should get following records:
I know you
you know
you may not know me
do i know you
Similarly, i need to return below records for criteria 'hello you':
Hello How are you
Just to say you Hello
Can Oracle Text help me here?
Thanks in advance for your help.
regards,
