Ok, I logged in and I installed the Query Monitor plugin which I said I needed.
I install Code Snippet (a second extremely useful plugin) and added a new snippet of code which alters directory search on your site. I think the results are exactly what you are looking for.
Give it a test and let me know.
ps. Query Monitor is reporting that Sabai quite a few errors. Mostly warnings and notices which is many cases are the worsts things that can be reported but several are stating that files can not be opened. You might want to report that to their support.
