tomtom, there actually *is* expert lotto feature that allows your AND filtering (pointed to me by other member of our expert lotto team).
e.g. if you want to get lines that have 1 to 2 numbers from number set A (e.g. 1,2,3,4,5) AND/OR 2 to 3 numbers from number set B (e.g. 34,35,36,40,41,42,49) then you can use the 'visual package page' filtering.
first click on the panel on the right the numbers from set A, the numbers will be highlighted in yellow in the table. then check boxes 3, 4, 5, 6 (leave boxes 0, 1 and 2 blank) and click 'remove match in'.
then reset the current number highlight (double click the last number in panel's header) and click in the panel the numbers from set B. then check boxes 1, 4, 5, 6 (leave 0, 2 and 3 blank) and click 'remove match in'.
the remaining lines have either 1-2 numbers from set A or 2-3 numbers from set B or numbers from both sets A,B or none among the numbers from both sets A,B

if you want to get lines that have 1 to 2 numbers from number set A (e.g. 1,2,3,4,5) AND at the same time 2 to 3 numbers from number set B (e.g. 34,35,36,40,41,42,49) then you can use the 'visual package page' filtering again
first click on the panel on the right the numbers from set A, the numbers will be highlighted in yellow in the table. then check boxes 0, 3, 4, 5, 6 (leave boxes 1 and 2 blank) and click 'remove match in'.
then reset the current number highlight (double click the last number in panel's header) and click in the panel the numbers from set B. then check boxes 0,1, 4, 5, 6 (leave 2 and 3 blank) and click 'remove match in'.
the remaining lines have both :the 1-2 numbers from set A together with 2-3 numbers from set B
this is the case where also "zero" plays its important role.
