Before we make too many assumptions here, we need to know a little bit more of what is going on.
Are the things you want to exclude always the same or is there a way for them to differ from one time to the next?
Are you always attempting to exclude from the same field or can the field differ from one time to the next?
Do you always attempt to filter from one field at a time or can your multiple exclusions apply to multiple fields?
Try to keep the answer in common business English and avoid the temptation to provide us with jargon.
