  "description": "<p></p><p>By analyzing ${e}^{+}{e}^{-}$ annihilation data corresponding to an integrated luminosity of $7.93\\text{}\\text{}{\\mathrm{fb}}^{-1}$, collected at the center-of-mass energy of 3.773 GeV with the BESIII detector, we search for the semileptonic decays ${D}^{0}\\to {K}^{-}\\eta {e}^{+}{\\nu }_{e}$, ${D}^{+}\\to {K}_{S}^{0}\\eta {e}^{+}{\\nu }_{e}$ and ${D}^{+}\\to \\eta \\eta {e}^{+}{\\nu }_{e}$ for the first time. We present evidence for ${D}^{0}\\to {K}^{-}\\eta {e}^{+}{\\nu }_{e}$ with a significance of $3.3\\sigma $. The branching fraction of ${D}^{0}\\to {K}^{-}\\eta {e}^{+}{\\nu }_{e}$ is measured to be $\\left(0.8{4}_{-0.34}^{+0.29}\u00b10.22\\right)\u00d7{10}^{-4}$. No significant signals are observed for the decays ${D}^{+}\\to {K}_{S}^{0}\\eta {e}^{+}{\\nu }_{e}$ and ${D}^{+}\\to \\eta \\eta {e}^{+}{\\nu }_{e}$ and we set the upper limits on their branching fractions.</p><p></p>",
