In order to index a certain content type's fields. I also use organic groups. So I need to index only the nodes that belong to say organic group with ID 12.
How could this be achieved? I have not seen anywhere in the GUI, a place I could set parameters for any field.
I.e.if I have a field with boolean values - 0 and 1, how could I restrict it to only index nodes that have the value 1 in this boolean field?
