Using multiple sub indexes in a catsearch query

Question

Hi,
I have a ctxcat index on a table with orgname as the indexed column and city and postal code as sub indexes.
I could do a
select *
from xxx_org_search_v
where 1 =1
and catsearch(org_name,'green*','postal_code=''38016''') > 0;
and
select *
from xxx_org_search_v
where 1 =1
and catsearch(org_name,'green*','city=''CORDOVA''') > 0;
but I how do I do this one?
select *
from xxx_org_search_v
where 1 =1
and catsearch(org_name,'green*','postal_code=''38016'' city=''CORDOVA''') > 0;
whats the syntax for acheiving the above?
Thanks
Guru
