Text :: Add Multi Indexes On One Table?

I been doing a little testing with indexing the contents of URLs (database v11.2.x.x).

ctx_ddl.drop_preference('TEST_URL');
ctx_ddl.create_preference('TEST_URL','URL_DATASTORE');
ctx_ddl.set_attribute('TEST_URL','Timeout','3600');

create index datastores_text on test_url_search ( doc ) indextype is ctxsys.context parameters ( 'Datastore TEST_URL' );

SELECT SCORE(1),DOC from TEST_URL_SEARCH WHERE CONTAINS(DOC, 'London', 1) > 0

This works. i like to more

e.g. multi words search e.g. ' London Games' where if London or games are present it return a URL with a score,

or

Search in the Chinese.

The only way I can see to do this is create different indexes as the attributes for 'URL_DATASTORE' are limited. If I can what does the 'Contains' statement look like?
