When constructing a query or a filter, you need to tell Access what to look for in each field. You do this by defining criteria - typing something (an "expression") into the Criteria cell of the query or filter grid. If you do not define any criteria for a particular field, Access assumes that you are applying no constraints and will display everything it has. This means that you only have to define criteria for those fields you are interested in. Here are some examples of the more common types of criteria. Often Access will complete the expression so that you need only type the text you want to match. Access Tips: Query and Filter Criteria
