Search function in Cydia

[Auryfael]

Hi
I have just jailbroken my Ipad, af installed Cydia. However, the search function doesn't seem to work, I can type something, but there is no result alt all. Not even when I post a single letter. I wish to install F.lux, but it is nowhere to be found.

Go to the home Cydia tab and hit Reload. Do you see anything there?
Do you see anything in Changes?
