We argue to search for them in the final states $\\Upsilon(1S,2S,3S)\\pi^+\\pi^-$, which are found to have anomalously large production rates at $\\Upsilon(5S)$. The enhanced rates for the dipionic transitions in the $\\Upsilon(5S)$-energy region could, besides $\\Upsilon(5S)$, be ascribed to $Y_b(10890)$, a state reported by the Belle collaboration, which may be interpreted as a tetraquark.
