We study the potential of CERN LEP II to unravel the existence of invisibly decaying Higgs bosons, predicted in a wide class of models. We perform a model-independent analysis, focusing our attention on the final state topologies exhibiting b{bar b} or scr(l){sup +}scr(l){sup {minus}} (scr(l)={mu} or e) pairs and missing energy. We carefully evaluate the signals and backgrounds, choosing appropriate cuts to enhance the discovery limits. Our results demonstrate that LEP II is capable of discovering such a Higgs boson for a wide range of masses and couplings. {copyright} {ital 1997} {ital The American Physical Society}
