We have been using CRM webclient UI for incident management. We added a custom flag field to incident forms called Requires Verify/Validate. If the solution to an incident was a program or config change then this flag needs to be checked showing the solution was verified and validated. 
What we would like to do now is use the search functionality in the Worklist to search for all incidents that have this field checked. How can I add this field as a search criteria?
This field is not listed in the configuration area. I would like to be able to add it so we can include this in the drop down area for search criteria.
