Something isn't being communicated well. Perhaps you are using an incorrect search expression, perhaps you haven't found the button that others have pointed you toward, or perhaps something else is going on.
The image below shows approximately what you should see, assuming your TBR column is a Yes/No column. The button pointed at on the right should be there if you have changed the search preferences. The search expression should contain the lookup name of your TBR column; mine is #cbhread. The value shown in the spreadsheet should equal the value in the search expression; in this case "yes" is the checked value.
Could you post an equivalent screen shot of what you are seeing?
