Double entry in the TOC seems logical. TOC is like a home page for the html,
not meant as searchable index. The bugreport I mentioned it because the TOC
might be processed and added to Index or fulltextsearch, thus poluting it.

According to 


lhelp utilizes fulltextsearch. Still I don't get two entries there either using
MS' viewer.  

But I think primarily basic search should use the index. (that is what the
textmode IDE does for context sensitive search).  I never worked on
fulltextsearch, I hardly know how it works.
