The  data recorded with the OPAL detector at $\sqrt{s}$ between $91$ and  
$209\,\mathrm{GeV}$ are used to search for Higgs Bosons in the Higgsstrahlung 
process $\mathrm{e^{+}e^{-}}\rightarrow\mathrm{ZH}$.
Hadronic decays of the Higgs boson into quarks or gluons, not necessarily into
b-quarks, are studied.
Decays into b-quarks can be suppressed in extended Higgs models, as 
for instance in Two Higgs Doublet Models  of type II (2HDM(II)). 
Therefore the development of decay flavour independent searches,
which are complementary to the usual Standard Model searches,
leads to more generality and model-independence.

Assuming a branching ratio into hadrons of 100\%, a
limit on the Higgsstrahlung cross section is derived as a function of
the assumed Higgs mass. Additionally, the results are interpreted within 
2HDM(II) models.
