well, the info is actually there already so i added a new option (that 
you then wikify) ...

\setupregister
   [index]
   [pagesegments=1:4,
    pagemethod=section]

\starttext

     \chapter {one} \section {alpha}

     x\index {whatever 1}x\index {whatever 2}x\index {whatever 2}x \page
     x\index {whatever 1}x\index {whatever 2}x\index {whatever 2}x \page

     \chapter {one} \section {alpha}

     x\index {whatever 1}x\index {whatever 2}x\index {whatever 2}x \page
     x\index {whatever 1}x\index {whatever 2}x\index {whatever 2}x \page

     \placeindex[n=1]

\stoptext

which then renders:

w
whatever 1 1.1, 2.1
whatever 2 1.1, 2.1

in next beta
