Deleting Index Markers

Hi:

When using the not-yet-fully-repaired Indexing function, a marker is
pre-pended to each instance of any word that is to be indexed.

How can I search for (and eliminate) these marks in one shot?

The reason is that if I add more names/words to the concordance file and
regenerate the index, each indexed word in the document automatically gets
an additional index mark, and this starts getting ugly very fast.

I would have thought this would happen automatically – or at least that I
would be given a choice of adding or replacing all index marks – but that
doesn’t seem to be the case.

Right now, I am using Version: 4.3.0.0.alpha0+ Build ID:
be4035d00f37c492494fa7860955b6d0868c7f77 on 64 bit Ubuntu 12.04LTS.

As usual, any help would be appreciated.
