 /**
- * The AnalysisModule is the main extension point for node and index level analysis components. The lucene classes
- * {@link org.apache.lucene.analysis.Analyzer}, {@link org.apache.lucene.analysis.TokenFilter}, {@link org.apache.lucene.analysis.Tokenizer}
- * and {@link org.apache.lucene.analysis.CharFilter} can be extended in plugins and registered on node startup when the analysis module
- * gets loaded. Since elasticsearch needs to create multiple instances for different configurations dedicated factories need to be provided for
- * each of the components:
- * <ul>
- *     <li> {@link org.apache.lucene.analysis.Analyzer} can be exposed via {@link AnalyzerProvider} and registered on {@link #registerAnalyzer(String, AnalysisProvider)}</li>
- *     <li> {@link org.apache.lucene.analysis.TokenFilter} can be exposed via {@link TokenFilterFactory} and registered on {@link #registerTokenFilter(String, AnalysisProvider)}</li>
- *     <li> {@link org.apache.lucene.analysis.Tokenizer} can be exposed via {@link TokenizerFactory} and registered on {@link #registerTokenizer(String, AnalysisProvider)}</li>
- *     <li> {@link org.apache.lucene.analysis.CharFilter} can be exposed via {@link CharFilterFactory} and registered on {@link #registerCharFilter(String, AnalysisProvider)}</li>
- * </ul>
- *
- * The {@link org.elasticsearch.indices.analysis.AnalysisModule.AnalysisProvider} is only a functional interface that allows to register factory constructors directly like the plugin example below:
- * <pre>
- *     public class MyAnalysisPlugin extends Plugin {
- *       public void onModule(AnalysisModule module) {
- *         module.registerAnalyzer("my-analyzer-name", MyAnalyzer::new);
- *       }
- *     }
- * </pre>
+ * Sets up {@link AnalysisRegistry}.
