Have you assigned the sourcetypes?
this app seems to be driven by macros. So what I would do, is take a look at the macros and run them separately in the search view. (run the search code, not the macro). In other words, take it apart a bit to see what might be out of alignment
The macros are found this way.
From the App Dashboard Screen
Select the Settings Menu>
Select the Advanced Search>
Select the Search Macros>
Examine the list and see if something jumps out... cut and past the Search code into the search view and run it. See what it gets you.
