Hi,

Ok, I could achieve something with this approach. But
it's not clear for me how to set the ZCatalog to
create an index from the result of an external method.
Can you please explain how to achieve this?

Also, the ZCatalog queries use an "and" chain for each
token provided (eg. if a query is requested for "a b
c" it will be interpreted as "a" and "b" and "c"), and
I'd like to implement an "or" chain in the queries.

Thanks for the help,

Daniel
