Eric, Unit tests should help you see how this can be used:
./contrib/analyzers/src/java/org/apache/lucene/analysis/shingle/ShingleFilter.java ./contrib/analyzers/src/java/org/apache/lucene/analysis/shingle/ShingleAnalyzerWrapper.java ./contrib/analyzers/src/java/org/apache/lucene/analysis/shingle/ShingleMatrixFilter.java ./contrib/analyzers/src/test/org/apache/lucene/analysis/shingle/ShingleAnalyzerWrapperTest.java ./contrib/analyzers/src/test/org/apache/lucene/analysis/shingle/TestShingleMatrixFilter.java ./contrib/analyzers/src/test/org/apache/lucene/analysis/shingle/ShingleFilterTest.java As for multi-word tokens, you just have to make sure they don't get injected before something that would remove any portion of them.
