Concordance Indexes
I implore you not to waste your time with a Concordance Index for most publications. It results in a huge pile of rubbish that is of very little use to the reader. And it takes nearly as long to make as it does to generate an index properly.

ah well that's what your link says and I had read it before. Look like the usual Microsoft rubbish. ok when its straightforward but for anything e;se you're screwed. I'll just have to miss out the bold and italic ones and use ordinary text
