Indexing multiple columns of multiple tables

Question

Hi,
I'm trying to index multiple columns of multiple tables.
As I have seen, the way to do this is using User_Datastore.
have the tables to share a (foreign)key? My tables have only 2 or 3 similar columns(description, tagnr...)
I want to get the different tagnr belonging to the same description etc.
Can I do this?
Has anyone a Samplecode indexing multiple tables?
Any suggestion would be helpful.

A USER_DATASTORE works like this:
create table A
( id number primary key,
textA varchar2(100));
create table B
( id number primary key,
textB varchar2(100));
procedure foo (rid in rowid, v_document in out varchar2)
v_textA varchar2(2000);
v_idA number;
v_textB varchar2(2000);
begin
select id, textA
into v_idA, v_textA
from A
where rowid = rid;
select textB
into v_textB
from B
where id = v_idA;
v_document := textA | | ' ' | | textB;
end;
create preferences for USER_DATASTORE
create index ...
on table A ( text) ...
you also can build on table B
This depends where you want the
trigger to be build to sync the
documents.
