Hi,

currently I have time to try out your suggestions. First I want try =
using the advice using "OrdinalPolicy".

But I have problems defining the Params FacetIndexingParams. How do I =
create those params with the required OrdinalPolicy?

I already searched a lot, but found no solution yet. Here is a small =
snipped of code for indexing:

List<CategoryPath> categories =3D new ArrayList<CategoryPath>();
for (String path : paths) {
  CategoryPath cat =3D new CategoryPath(FIELD_GROUP_ID + "/" + path, =
'/');
  categories.add(cat);
}
for (CategoryPath path : categories) {
  taxoWriter.addCategory(path);
}
...
// TODO FacetIndexingParams need to be added here...
FacetFields ff =3D new FacetFields(taxoWriter);
ff.addFields(doc, categories);

Thanks a lot in advance!
-Danny

Hi,

which version of Lucene?

Check the OrdinalPolicy you are using in FacetIndexingParams at indexing
time.

I think you should use: NonTopLevelOrdinalPolicy in lucene 3.6.1 or
OrdinalPolicy.ALL_BUT_DIMENSION in lucene 4.2.1



Nicola.
