I realise that there is a workaround for the sample above, using the 
literal ASCII string in [] which makes this specific example work. 
Unfortunately this doesn't make everything work correctly in a larger 
document. I'm now seeing two other specific behaviours as well:

1. When there is a range and a single entry, the range is sometimes 
listed first in the index, even if the single entry is many pages before 
it - i.e. 282-283, 170

2. On other occasions where a range and a single entry exist, I end up 
having a strange three-way range in the index - like 282-283-349. The 
last reference should be just a single one on its own.

It's really difficult to post a minimal file for these because they only 
occur when the whole text is processed (several hundred pages). I have 
just synchronised my tree this morning and no difference is made.

Any help, especially today, VERY gratefully received.

Urgent index problem

[Duncan Hothersall]

I am one night from a deadline and I have just noticed that my index is 
silently ignoring some entries... Help!!

The following demonstrates the problem (tested on live.contextgarden.net):

--
\starttext
\startregister[index]{this term+in+particular} This term is discussed 
from the start of this page.\page[yes]
Some more text about the term, and another page.\page[yes]
And the end of the info about that term. \stopregister[index]{this 
term+in+particular}\page[yes]
A page unrelated to that term.\page[yes]
\index{this term+in+particular} And then another page on exactly the 
same term.\page[yes]
\placeindex\page[yes]
Disaster! The entry on page 5 has been eaten!
\stoptext
--

So we have the same terms referenced as a span over pages 1 to 3, and as 
a single entry on page 5. But only the span appears, not the second 
entry! The .tuo file contains:

\registerentry{index}{t}
\registerentrya{index}{this term}
\registerentryb{index}{in}
\registerentryc{index}{particular}
\registerfrom{index}{,}{1}{2::0:0:0:0:0:0:0::1}{1}
\registerpage{index}{,}{3}{2::0:0:0:0:0:0:0::5}{5}
\registerto{index}{,}{2}{2::0:0:0:0:0:0:0::3}{3}

so it looks like the sorting of these by page numbers has broken, and 
ConTeXt thinks that page 5 is between pages 1 and 3.

I hope someone can help...
