如何使用Hibernate Lucene Search进行不区分大小写的挪威字符（Æ，Ø和Å）排序？

如何使用Hibernate Lucene Search进行不区分大小写的挪威字符（Æ，Ø和Å）排序？

您可以

org.apache.lucene.collation.CollationKeyFilter

在Hibernate
Search版本4.3.0.Final中使用类。创建自己的归类过滤器工厂：

import org.apache.lucene.analysis.TokenStream;import org.apache.lucene.collation.CollationKeyFilter;import org.apache.solr.analysis.baseTokenFilterFactory;import java.text.Collator;import java.util.Locale;public final class NorwegianCollationFactory extends baseTokenFilterFactory {    @Override    public TokenStream create(TokenStream input) {        Collator norwegianCollator = Collator.getInstance(new Locale("no", "NO"));        return new CollationKeyFilter(input, norwegianCollator);    }}

并在AnalyzerDef中使用以下整理工厂：

@AnalyzerDef(name = "myOwnAnalyzer",tokenizer = @TokenizerDef(factory = KeywordTokenizerFactory.class),filters = {    @TokenFilterDef(factory = ASCIIFoldingFilterFactory.class),    @TokenFilterDef(factory = LowerCaseFilterFactory.class),    @TokenFilterDef(factory = PatternReplaceFilterFactory.class, params = {        @Parameter(name = "pattern", value = "('-&\.,\(\))"),        @Parameter(name = "replacement", value = " "),        @Parameter(name = "replace", value = "all")    }),    @TokenFilterDef(factory = PatternReplaceFilterFactory.class, params = {        @Parameter(name = "pattern", value = "([^0-9\p{L} ])"),        @Parameter(name = "replacement", value = ""),        @Parameter(name = "replace", value = "all")    }),    @TokenFilterDef(factory = TrimFilterFactory.class),    @TokenFilterDef(factory = NorwegianCollationFactory .class)})public class KikaPaya implements Serializable {
