Something wrong with search engine

There is something wrong with the search engine. It is omitting shows.
I was browsing shows and noticed that I was missing a few episodes of a few shows over the last few weeks.
When I searched for the show, I noticed that the show that I originally browsed wasn't in the search.

:(
I hope this can be fixed.
This is still my favorite nzb site.
Thank you,
M

Edit: I even noticed some shows that I could browse, but then when I search for them it says no results found.

There's a ghost in the machine....

There are a few threads on this, no conclusive answers but the index seems to either miss or drop things... :(
