La esperanta frazo estis ŝanĝita.
Ĝisdati vian rusan frazon se vi bonvolas.

Marcelo,
Mi ne komprenas la novan Esperantan frazon...

Devus esti:
Kion vi serĉas?

(ĉiel ajn, la rusa frazo devos esti ŝanĝita, ĉar ne temas pri "kiu", sed pri "kio").

It seems it was just like for a moment.
I'm not very sure how should it be, so why don't you suggest it yourself?

The problem is, "Kion vi serchas?" (i.e., what are you looking for?) already exists there; sigfrido changed his own original sentence, but the new variant already existed, so maybe he changed it again, on the same day. These are only my assumptions, I don't really know what happened there.

It will be too philosophical to start discussing all that in the comment box of the relevant sentence. What do you suggest?

o_O
I don't know, perhaps, suggesting ae5s's opinion for unlinking this sentence, and trust the criterion of the owner of the Esperanto sentence, and any future comments on it.
Plus, linking "Kion vi serĉas?"
http://tatoeba.org/deu/sentences/show/543157
to "Wonach sucht ihr?".
ĉu ne?

Jes, mi subtenas tion.
Yes, I concur.

So, to sum up:
Pri kio vi serĉas?
should be unlinked, and stand alone.

Kion vi serĉas?
should be linked to "Wonach sucht ihr?"
and also to the current sentence.

Last but not least, the current sentence should be changed to conform with "what" rather than "who".

Agree
