在休眠搜索中使用现有分析器AnalyzerDiscriminator [英] Use existing analyzer in hibernate search AnalyzerDiscriminator

问题描述

@Entity
@Indexed
@AnalyzerDefs({
  @AnalyzerDef(name = "en",
    tokenizer = @TokenizerDef(factory = StandardTokenizerFactory.class),
    filters = {
      @TokenFilterDef(factory = LowerCaseFilterFactory.class),
      @TokenFilterDef(factory = EnglishPorterFilterFactory.class
      )
    }),
  @AnalyzerDef(name = "de",
    tokenizer = @TokenizerDef(factory = StandardTokenizerFactory.class),
    filters = {
      @TokenFilterDef(factory = LowerCaseFilterFactory.class),
      @TokenFilterDef(factory = GermanStemFilterFactory.class)
    })
})
public class BlogEntry {

    @Id
    @GeneratedValue
    @DocumentId
    private Integer id;

    @Field
    @AnalyzerDiscriminator(impl = LanguageDiscriminator.class)
    private String language;

    @Field
    private String text;

    private Set<BlogEntry> references;

    // standard getter/setter
    // ...
}

public class LanguageDiscriminator implements Discriminator {

    public String getAnalyzerDefinitionName(Object value, Object entity, String field) {
        if ( value == null || !( entity instanceof Article ) ) {
            return null;
        }
        return (String) value;

    }
}

从参考文档中，
如何使用动态定义的现有分析器(如org.apache.lucene.analysis.cjk.CJKAnalyzer和en和de)?我只能在这里返回分析器的名称，当我返回CJKAnalyzer时，我将得到未定义的分析器.

From Reference Doc,
How can I use an existing analyzer like org.apache.lucene.analysis.cjk.CJKAnalyzer along with en and de ones which I have dynamically defined? I can only return name of the analyzer here and when I return CJKAnalyzer I get not defined analyzer.

如何将现有分析仪添加到分析仪定义中?

How can I add an existing analyzer to my analyzer definitions?

推荐答案

这是一个很好的问题，我很惊讶以前没有人问过这个问题.

That's an excellent question, and I'm surprised noone asked that before.

答案是不可能的.

我已经在项目中打开了功能请求以对此进行改进:

I have opened a feature request on the project to improve on this:
