Search for empty property fields in SharePoint 2010?

Question

Is it possible to search (e.g. via the property picker in the advanced search dialog) for all items that have a specific property field which is empty?

For example: All items with an emtpy title field.

Answer 1

The advanced search dialog does not support this. You will need to implement a custom search Web part that leverage the NULL Predicate in an SQL search query.
