æ、ø、å 是挪威字母表中最新的字母
æ, ø, å are latest letters in the norwegian alphabet
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z Æ Ø Å
当我们尝试使用 Hibernate Lucene 对其进行排序时,然后 Å clubs with A
、Ø clubs with Ø
、Æ clibs with A
即错误的.例如:
When we try to sort it using Hibernate Lucene then Å clubs with A
, Ø clubs with Ø
, Æ clibs with A
which is wrong. For example:
当前结果:
阿鲁,奥阿鲁,巴鲁,扎鲁,
Aaalu, Åaalu, Baalu, Zaalu,
预期结果:
阿鲁,巴鲁,扎鲁,阿鲁,
Aaalu, Baalu, Zaalu, Åaalu,
以下是工作代码:
@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)
}
)
public class KikaPaya implements Serializable {
@Fields({ @Field(index = Index.YES, store = Store.YES), @Field(name = "KikaPayaName_for_sort", index = Index.YES, analyzer = @Analyzer(definition = "myOwnAnalyzer")) })
@Column(name = "NAME", length = 100)
private String name;
主要:
FullTextEntityManager ftem = Search.getFullTextEntityManager(factory.createEntityManager());
QueryBuilder qb = ftem.getSearchFactory().buildQueryBuilder().forEntity( KikaPaya.class ).get();
org.apache.lucene.search.Query query = qb.all().getQuery();
FullTextQuery fullTextQuery = ftem.createFullTextQuery(query, KikaPaya.class);
fullTextQuery.setSort(new Sort(new SortField("KikaPayaName_for_sort", SortField.STRING, true)));
fullTextQuery.setFirstResult(0).setMaxResults(150);
int size = fullTextQuery.getResultSize();
List<KikaPaya> result = fullTextQuery.getResultList();
for (KikaPayauser : result) {
logger.info("KikaPaya Name:" + user.getName());
}
以下是 Lucene 的版本(我无法更改):
Following are versions of Lucene (which i cannot change):
<hibernate.version>4.2.8.Final</hibernate.version>
<hibernate.search.version>4.3.0.Final</hibernate.search.version>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>4.2.8.Final</version>
</dependency>
<dependency>
<groupId>org.apache.lucene</groupId>
<artifactId>lucene-core</artifactId>
<version>3.6.2</version>
</dependency>
<dependency>
<groupId>org.apache.lucene</groupId>
<artifactId>lucene-analyzers</artifactId>
<version>3.6.2</version>
</dependency>
谁能提出获得正确结果的方法?
Could anyone suggests the way to get correct results?
您可以在 Hibernate Search 4.3.0.Final 版本中使用 org.apache.lucene.collation.CollationKeyFilter
类.创建您自己的排序规则过滤器工厂:
You can use org.apache.lucene.collation.CollationKeyFilter
class in Hibernate Search version 4.3.0.Final. Create your own collation filter factory:
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);
}
}
并且在您的 AnalyzerDef 中使用此排序规则工厂:
And the use this collation factory in your AnalyzerDef:
@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 {
