\index{sample}

\index{fun+games}\index{fun+stuff}

%\index{fun}

\seeindex{fun}{sample} % now with heading (as it should be)

\seeindex{fun}{blah} % not shown

\seeindex{fun}{humbug} % not shown

\seeindex{fun}{bug} % not shown

\seeindex{fun+games}{entertainment} % not shown

\placeindex[n=1]

\stoptext

When I generate the indices for my book, \seeindex{A}{B} works only if it is a unique x-ref and A is a heading. Multiple x-refs to the same heading fail as do x-refs to subheadings.
