  We present a search for Higgs bosons in multilepton final states in pp-bar
collisions at sqrt(s)=1.96 TeV recorded with the D0 detector at the Fermilab
Tevatron Collider, using the full Run II data set with integrated luminosities
of up to 9.7 fb-1. The multilepton states considered are two electron plus
muon, electron with two muons, muon with two hadronic tau leptons, and
like-charge electron-muon pairs. These channels directly probe the HVV (V=W,Z)
coupling of the Higgs boson in production and decay. The muon with two hadronic
tau lepton channel is also sensitive to H to tau lepton pair decays. Upper
limits at the 95% C.L on the rate of standard model Higgs boson production are
derived in the mass range 100 <= M_H <= 200 GeV. The expected and observed
limits are a factor of 6.3 and 8.4 above the predicted standard model cross
section at M_H=125 GeV. We also interpret the data in a fermiophobic Higgs
boson model.
