Examples of QueryScorer

org.apache.lucene.search.highlight.QueryScorer
{@link Scorer} implementation which scores text fragments by the number ofunique query terms found. This class converts appropriate {@link Query}s to {@link SpanQuery}s and attempts to score only those terms that participated in generating the 'hit' on the document.

Examples of org.apache.lucene.search.highlight.QueryScorer

        int docid=scoreDoc.doc;
        
        Document doc=multiReader.document(docid);
        String content=doc.get("content");
        
        Scorer qs=new QueryScorer(q);
        
        SimpleHTMLFormatter formatter=new SimpleHTMLFormatter("<span class=\"hl\">","</span>");
        Highlighter hl=new Highlighter(formatter,qs); 
        String[] fragments=hl.getBestFragments(analyzer, "content",content, 1);
