Welcome to the forum. You post is a bit confusing; are you
using RoboEngine in some manner, or did you mean using RoboHelp to
publish a Winhelp system? Perhaps you are building a Winhelp 2000
system, a speciality of RoboHelp? Either way, RoboEngine shouldn't
be involved.
If you are indeed creating Winhelp files, the search results
are not very open to customization. One
might be able to tap into the search of an htmlhelp file
(.chm). WebHelp's search could be made to do it, with some custom
scripting. Not sure about WebHelp Pro, which uses the RoboEngine.
More details, please.
