Indexing multiple Tables

Question

Hi !
I´ve got a question. Is it possible to create an index with three base tables that hold the information to be indexed.
table1 {
proj_id number,
name varchar2,
thema varchar2
table2 {
proj_id number,
abstract clob}
table3 {
proj_id number,
gutachten clob
I want to index name, thema, abstract and gutachten. The examples i found use only one table to index. Is it possible to create a view with all the rows needed and then to index the view?
Thanks
Holger

You can build a USER_DATASTORE on your 'master' table (table1). Then build a procedure which collects the information from you other two tables:
This will show you the way:
procedure my_datastore ( in v_rowid
v_proj_id number;
v_name varchar2;
v_abstract CLOB;
v_gutachten CLOB;
v_result CLOB;
select proj_id, name
into v_proj_id, v_result
from table1
where rowid = v_rowid;
select abstract
into v_abstract
from table2
where proj_id = v_proj_id;
select gutachten
into v_gutachten
from table3
where proj_id = v_proj_id;
v_result = v_name || v_abstract || v_gutachten;
