According to the example here: https://github.com/apache/lucene-solr/blob/master/solr/core/src/test-files/solr/collection1/conf/stemdict.txt The lines need to be tab separated. I'm betting that you're running into this bug, which is still unresolved: https://issues.apache.org/jira/browse/LUCENE-4545 The source file you have referenced uses spaces. If those are still in your file, it isn't going to work. It appears that the way the code is written (and is STILL written even in master, which will one day be version 8.0), the separator must be a SINGLE tab. I have confirmed that multiple tabs or any number of spaces isn't going to work properly. I will see what I can do about getting the bug fixed, but for now you're going to have to fix all the separators in your dictionary file. Thanks, Shawn
