Check it out! We just released a new How Do I video on the LightSwitch Developer Center. I created this one based on suggestions from you so I hope you like it!
In this video you will learn a couple techniques you can use when creating custom search screens. You will see how to create custom queries to provide specific search criteria with limited choices, search within a range of dates, as well as provide a filter by related parent records.
