Oracle Text, multi_column_datastore describe index

Question

Referring to Re: Oracle Text, ctxsys.context problem with number column
In TOAD or SQL Navigator you can click on some object (like table, index) and click on tab "script" where is generated the code to create it.
Assuming that I am a person who sees the index for the first time where/how I can find multi_columns/parameters with which the index was created ?
For example:
exec ctx_ddl.drop_preference( 'myds' );
exec ctx_ddl.create_preference( 'myds', 'MULTI_COLUMN_DATASTORE' );
exec ctx_ddl.set_attribute( 'myds', 'COLUMNS', 'item_barcode, item_title, item_subtitle' );
CREATE INDEX i_index_test
   ON item (item_title)
   INDEXTYPE IS ctxsys.context
   PARAMETERS ( 'datastore myds' );And script says:
CREATE INDEX PLSQL.I_INDEX_TEST ON PLSQL.ITEM
(ITEM_TITLE)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('datastore myds')
NOPARALLEL;
Where I can find datastore "myds" ?

Answer 1

You can use ctx_report to get all the information about an index.
I use it from SQL*Plus like this:
set pagesize 0
set heading off
set trimspool on
set long 500000
spool index.sql
select ctx_report.create_index_script('MyIndexName') from dual;
spool offThe only thing this won't give you is the source for any procedures used in the user_datastore. You can get that from user_sources.
