如果它们与搜索查询匹配,我想突出显示整个未分析的字段 索引实体如下所示:
@Entity
@Indexed
@AnalyzerDef(
name = "documentAnalyzer",
tokenizer = @TokenizerDef(factory = StandardTokenizerFactory.class),
filters = {
@TokenFilterDef(factory = ASCIIFoldingFilterFactory.class),
@TokenFilterDef(factory = LowerCaseFilterFactory.class),
@TokenFilterDef(
factory = StopFilterFactory.class,
params = {
@Parameter(name = "words", value = "stoplist.properties"),
@Parameter(name = "ignoreCase", value = "true")
}
)
}
)
public class Document {
...
@Field(analyze = Analyze.NO)
private String notAnalyzedField; // has "x-xxx-xxx" format
@Field(analyze = Analyze.YES)
private String analyzedField;
}
假设我有一个Document
notAnalyzedField: "a-bbb-ccc"
,然后我运行一个具有相同值的搜索查询,并使用以下代码突出显示搜索结果:
String highlightText(Query query, Analyzer analyzer, String fieldName, String text) {
QueryScorer queryScorer = new QueryScorer(query);
SimpleHTMLFormatter formatter = new SimpleHTMLFormatter("<span>", "</span>");
Highlighter highlighter = new Highlighter(formatter, queryScorer);
return highlighter.getBestFragment(analyzer, fieldName, text);
}
因此,我得到以下代码段:"a-<span>bbb</span>-<span>ccc</span>"
这似乎是合理的,因为分析器将a
符号视为停用词并将-
视为分隔符并且不突出显示它们。但我无法弄清楚如何在突出显示此字段时避免使用分析器。 Highlighter
课程中有一些方法需要TokenStream
而不是Analyzer
,但我不确定如何使用它们。
我想要实现的结果是整个突出显示的字段:"<span>a-bbb-ccc</span>"
有没有办法用hibernate-search来实现这个目标?
答案 0 :(得分:1)
您的分析仪来自哪里?
您可能希望从Hibernate Search获取它:
FullTextEntityManager em = /*...*/;
Analyzer analyzer = em.getSearchFactory()
.getAnalyzer(Document.class);
highlightText(query, analyzer, fieldName, text);
如果不起作用,请尝试使用KeywordAnalyzer
:highlightText(query, new KeywordAnalyzer(), fieldName, text);
