Difference between CategoryPath and Plain FacetFields with hierarchy
Hi,
I am new to Lucene faceting and taxonomy. I saw few examples in some blogs
and in facets guide. Some have used CategoryPath with TaxonomyWriters,
TaxonomyReaders and FacetSearchParams. Some have used FacetFields without
using taxonomyWriters and TaxonomyReaders. What is the difference between
both these approaches? What is the recommended approach to to create a
faceted search application? For so called two different approaches please
refer to [1] and [2]

I don't think so: you must split it yourself.

Thanks Michael,
I am going to use FacetFields/FacetsConfig. So using FacetFields we can
define a hierarchy like below.
doc.add(new FacetField("Publish Date", "2012", "1", "7"))
Is it possible to use FacetFields like this, as we could do with
CategoryPath?
doc.add(new FacetField("Publish Date", "2012/1/7"))

The facets API changed in 5.0, from CategoryPath/FacetSearchParams to
FacetFields/FacetsConfig.

Hi,
Any help on this? Or Can someone point me to Faceted User guide of 4.10.3.
I cannot find it. Is it only available for Older version?
