Here, we report the first search for the $J^{PC}=0^{--}$ glueball in $\mathrm{{\rm Y}}\left(1S\right)$ and $\mathrm{{\rm Y}}\left(2S\right)$ decays with data samples of $(102\pm 2)\times 10^6$ and $(158\pm 4)\times 10^6$ events, respectively, collected with the Belle detector. No significant signals are observed in any of the proposed production modes, and the 90% credibility level upper limits on their branching fractions in $\mathrm{{\rm Y}}\left(1S\right)$ and $\mathrm{{\rm Y}}\left(2S\right)$ decays are gained. The inclusive branching fractions of the $\mathrm{{\rm Y}}\left(1S\right)$ and $\mathrm{{\rm Y}}\left(2S\right)$ decays into final states with a ${\chi }_{c1}$ are measured to be $\mathcal{B}\left(\mathrm{{\rm Y}}\right(1S)\to {\chi }_{c1}+\text{anything})=(1.90\pm 0.43(\text{stat})\pm 0.14(\text{syst}\left)\right)\times {10}^{-4}$ with an improved precision over prior measurements and $\mathcal{B}\left(\mathrm{{\rm Y}}\right(2S)\to {\chi }_{c1}+\text{anything})=(2.24\pm 0.44(\text{stat})\pm 0.20(\text{syst}\left)\right)\times {10}^{-4}$ for the first time.
