Calm down m8, he maybe aint got time to log on to the test server, ok what i know from reading up on this, the short searches dont yield good results, the medium and long were best percentages to fing eggs (cant remember what they were but they were highish) obviously the longest search wasnt good cause of the time it takes for them to come home.
So medium and long searches are the way to go, if your explorers can find easter adventures well then it may be better to alternate between treasure and adventure searches ( didnt find the adventure find rate at easter so cant tell u anything about that).
Here is the link for the exact info
