=== Troubleshooting ===
* Everything looks correct but filtering returns no results:
** Ensure that the string you are trying to filter by matches what is returned as the DisplayValue.
** If the property is a INT / DBL (Integer or Double) type: The string comparison doesn't work directly with non-string types. Check the [[HowTo:Implement_Custom_Filtering#Other_Property_Types|Other Property Types]] section.
