The Lucene In Action book has an excellent chapter on Analysers - well worth a read. Of particular interest is some code that allows you to see how a given Analyser tokenises an input string. You can download the source code from the book (http://www.lucenebook.com/LuceneInAction.zip). If you unzip this file you will find a directory called "LuceneInAction/src/lia/analysis" and in there is a class called AnalyzerDemo (which depends in AnalyzerUtils). Compile this and run to see how the Analysers work. Put in your hyphenated strings to see how they work too.
