Yes, queries are additive. This means that specifying selections in more than one field means that your results will be of those who match all of the selections specified. I.E. Setting the type drop down to "Parent" and the has email menu to "No" will give you only members who are email-less parents.
NOTE: when you select more than one team in the "Position" or "Teams" lists, the selections are put together with the "Or" operation-- meaning that any member belonging to any one of the selected teams (or positions) will be selected. This only applies to this list, however. The selected teams are still put together with the other fields on the form, with the "And" operator as previously explained.
