combine search filed with a OR condition / code of search

Hi,

is there a way to combine two or more fields in a search (freeform, named or mask) with a OR condition instead of the standard AND condition ?

What I I am looking for is something like this sample as code:

- (Supplier = 'ABC' ) OR (produktid = 123)

- (Supplier = 'ABC' and fieldA=1) OR (produktid = 123)

Is it also possible to have a code for a search like in sql ? Look like we have a field code in a namedsearch but not sure if it is interpreted in a way like thiis.

Kind Regarads
