problems with keyword search

I haven't seen the dialog box that you sent me a picture of , so I'll explain how I generate my search. With the Bridge program open I "Sort By Keywords" . I also open up the assigned keyword collumn and highlite the specific keyword then right click and open a drop down box that gives me a find option then I click on it . This opens another dialog that shows the hard drive containing all the sub-folders where the picture files are contained . I also check the box to include all sub-folders in the search . But unless I hightlite the specific folder that contains a picture that is tagged with the keyword I'll get a message saying " No Items To Display"
