Digging a bit deeper, I realized that the dependencies point to Lucene 3.6.0 which is the reason that Lucene 4.0 indexes are not recognized. According to https://issues.apache.org/jira/browse/MAHOUT-1112 Mahout is just about to get ready for Lucene 4.0 and basically it should work. However, if I look at the Mahout trunk (http://svn.apache.org/viewvc/mahout/trunk/), the dependencies are still set to: <properties> <skipTests>false</skipTests> <maven.clover.multiproject>true</maven.clover.multiproject> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <hadoop.version>1.0.4</hadoop.version> <lucene.version>3.6.0</lucene.version> </properties> Is there a way to build and to use any actual version with Lucene 4.0? thanks, --tomw
