Mike,

I've not attempted what you're trying to do, but have you considered a couple of things? If you've already done this, sorry for stating the obvious, but your examples below don't include all the details.

">" is a reserved character, used for the threshold
comparator.

If you created your XML Section Groups as the Auto_Section_Group type, the InterMedia docs say "Empty tags, processing instructions, and comments are not indexed."

Did you create a Zone Section named publisher?

Just a few thoughts as to why your queries aren't working.

We're using InterMedia's XML section indexing (Oracle8.1.6.3), and mostly it
works fine. However, I think it's indexing technique means that you:
(i) cannot search for tags, eg contains(doc,'<bold>',1); (ii) cannot search for documents that have an empty tag (eg <bold></bold>).
In both cases wildcard expansion doesn't work; for example: SQLPLUS> select doc from mytable where contains (doc, '% within
publisher',0)>0;

ERROR at line 1:

ORA-29902: error in executing ODCIIndexStart() routine
ORA-20000: interMedia Text error:
DRG-50937: query too complex
DRG-51030: wildcard query expansion resulted in too many

terms

Does anyone know of a way to do either (i) or (ii).

Many thanks, Mike Monaghan
