If you use check boxes label them (Both/True/False) to help remind users the 3 states.
That is what I have done and the users are OK with this.

Subject: [Vantage] Re: filter bit fields with tracker in dashboard
Epicor Support explained to me that using checkboxes as Tracker View search prompts doesn't work well since checkboxes support three states vs just two. Their recommendation was to create a calculated field that showed string values of 'true' or 'false' based on the original logical value. Then create a search prompt field based on that calculated field. I will usually display the original logical field and not the calculated field in the grid so the checkboxes are displayed but then create the search prompt based on the calculated field.
