Obito's left Sharingan was taken away and transplanted to Kakashi, who stayed alive and well. And Obito's right half of his body got crushed by huge boulders, it's hart for a normal man to believe something could remain from it (even Madara admitted that his right eye survival already was a miracle). So this sole valuable thing in Obito's body was thought to be taken from him/destroyed, that's why there was no point in searching for his body (if someone searched for it at all)/
