Are your sure?

  The "Managable PathIndex" splits a string string at '/' 
  (alternatively it takes a sequence) and indexes the result
  in a way to support quite efficiently subpath searches.

  Thus, it is applicable, if "filename-splitting" means splitting
  at "/' (or you use some arbitrary splitting beforehand)
  *AND* (more importantly) if one is interested in subpath
  queries.

  If the second condition is not given, as KeywordIndex may do
  as well (again a "Managable KeywordIndex" would allow the splitting
  to be formulated as a normalizer).
