The documentation of a function with multiple methods is duplicated.

```julia
"""
doc of f
"""
f(m::AbstractMatrix) = g(m)
f(r::AbstractVector) = g(h(r))

```

searching for the doc of the function

```julia
help?> f

```

results in

```julia
  doc of f
  ────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
  doc of f

```

I can’t reproduce this, probably you have attached a docstring to something else called `f` in that same Julia session.

Note also that if you just want to attach the docstring to a function rather than a method you can do

```julia
"""
doc of f
"""
function f end

f(m::AbstractMatrix) = g(m)
f(r::AbstractVector) = g(h(r))

```

for example.

I don’t have another symbol with that name. But that does not matter, as your suggestion of adding an empty function solved the problem  
Thanks
