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
