Thanks for the help orange, but I found the solution here.
Code:
SELECT [Example Data].ID, [Example Data].[StarDate], [Example Data].[EndDate]
FROM [Example Data]
WHERE ((([Example Data].[StarDate])<[Forms]![DateSearch]![EndDate]) AND (([Example Data].[EndDate])>[Forms]![DateSearch]![StartDate]));
or for the non-SQL savvy (like me):
Under StarDate, put in the Criteria field: "<[Forms]![DateSearch]![EndDate]." Under EndDate, put in the Criteria field: ">[Forms]![DateSearch]![StartDate]"
Seems so simple now that I have it figured out!
