We are going to be building a form with Umbraco 7.1 and MVC and we are going to be getting the Prevalues from checkbox datatypes we set up to show on the frontend through a simple form.

We found how to get the Prevalues form our Datatypes through Razor using this

var dataTypeId = umbraco.cms.businesslogic.datatype.DataTypeDefinition.GetAll().First(d=> d.Text == "DataTypeName").Id;

var preValues = PreValues.GetPreValues(dataTypeId).Values;
var enumerator = preValues.GetEnumerator();
while (enumerator.MoveNext())
{
    var preValueText = ((PreValue)enumerator.Current).Value;
    <option>@preValueText</option>
}

Our nodes have the values from the datatypes defined within them.

How would be filter the Nodes by the prevalues selected from a form submission?  Meaning, how would we match nodes by the selected values.  

Example: 

Dataype 1 - Checkbox list
DT1 Option 1
DT1 Option 2
DT1 Option 3

Dataype 2 - Checkbox list
DT2 Option 1
DT2 Option 2
DT2 Option 3

How would we get or filter all nodes, on form submission, that match Datatype 1 and Datatype 2 options?

Thnaks in advance.
