From what I gather, because there are only two acknowledged references to a resurecction in the OT (Isaiah 26:13 and Daniel 12:2) and they are of a somewhat late date, a lot of scholars have suggested that the resurrection is of Persian descent. As a result, we find little about it in the writings.
Secondly, and I may have the fuzzy end of the lollypop here, resurrection in a Jewish sense was more about nationhood, then about individuals. Once the Jews were restored to their homeland, the dead would be resurrected.
