The HyCLAS experiment at Jefferson Lab is a program to search for new and unusual mesons produced via photoproduction. The strangeonia sector is poorly known and a main component of this program is a search for new strangeonium states. The reaction {gamma}p{yields}p{phi}{eta} is an ideal channel to look for strangeonium states due to the strangeness content of both the {phi} and {eta}. The data was acquired at the JLAB CLAS facility using a 4-5.5 GeV tagged photon beam. The {phi} meson is identified via the K{sup +}K- decay. The recoil proton is observed in the CLAS spectrometer and the {eta} meson is identified through the missing mass. Also of interest is the search for strangeonia decaying to {phi}{pi}{sup 0} and {phi}{omega}. These channels are OZI suppressed for qq-bar mesons and an observation of a meson decaying to these channels would provide a strong evidence of mesons beyond qqa-bar. Preliminary results describing the data quality, kinematics and dynamics will be shown.
