Import FilterLeafReader pylucene 4.9

I use PyLucene 4.9.0-0 for a school project and I need to use FilterLeafReader but I can't figure out how to import this class.

I tried from org.apache.lucene.search import FilterLeafReader but i receive an import error.

Solution

  • FilterLeafReader does not exist in Lucene 4.9, and so is not available in PyLucene 4.9.

    AtomicReader classes were renamed LeafReader in 5.0, so you should be using FilterAtomicReader instead. Also, in either case, it's in org.apache.lucene.index, not org.apache.lucene.search
