{
var query = GetQueryParser(highlightField).Parse(luceneRawQuery);
var scorer = new QueryScorer(searcher.Rewrite(query));
var highlighter = new Highlighter(HighlightFormatter, scorer);
var tokenStream = HighlightAnalyzer.TokenStream(highlightField, new StringReader(value));
string bestFragments = highlighter.GetBestFragments(tokenStream, value, MaxNumHighlights, Separator);
return bestFragments;
}示例2: Weight
/// <summary>Expert: Constructs and initializes a Weight for a top-level query. </summary>
public virtual Weight Weight(Searcher searcher)
