TLDR; fix is available: I've now revised the FacetExample.py to use the new API - it's tested to work with pylucene-4.8.0-1 The source can be found here: https://dl.dropboxusercontent.com/u/4384120/Python/FacetExample.py Andi, can you please update the file in the repo? thanks. details: I should correct myself. The FacetExample was 'ported' to 4.x (with new fully qualified imports) already. However in Java Lucene Release 4.7.0 [2014-02-26] some API Changes did break the code: LUCENE-5339: The facet module was simplified/reworked to make the APIs more approachable to new users. Note: when migrating to the new API, you must pass the Document that is returned from FacetConfig.build() to IndexWriter.addDocument(). (Shai Erera, Gilad Barkai, Rob Muir, Mike McCandless) see https://issues.apache.org/jira/browse/LUCENE-5339 for details! (This was really a good and needed simplification of the Facet API!) Some notes for those interested in facet search in Lucene: - there are some Java samples available with Lucene Java, e.g. http://svn.apache.org/repos/asf/lucene/dev/branches/lucene_solr_4_8/lucene/demo/src/java/org/apache/lucene/demo/facet/SimpleFacetsExample.java (which I took as a reference) - back in 4.4 there was some good documentation (besides Javadocs) - the "Apache Lucene Faceted Search "User's Guide http://lucene.apache.org/core/4_4_0/facet/org/apache/lucene/facet/doc-files/userguide.html I can't find it for more recent versions though and according to Changelog it was removed with 4.5 because it's outdated: LUCENE-4894: remove facet userguide as it was outdated. Partially absorbed into package's documentation and classes javadocs. (Shai Erera) (still think it's partially useful introductory reading though...) - developer hint: whereas in Java you can write doc.add(new FacetField("Publish Date", "2010", "10", "20")); here "Publish Date" is the 'dimension' and "2010", "10", "20" is the 'path' in Python you need to declare the path as an array argument: doc.add(FacetField("Publish Date", ["2010", "10", "20"])) Java introduced 'varargs' feature to pass unspecified number of argument to a method in JDK 5.0. Python can do similar by using the *args which can be passed a list of arguments - as positional arguments. Seems however JCC does for some (probably good) reason not map Java varargs to python *args. regards, Thomas
