Lucene.net-如何从每个匹配中提取文本的小片段

http://quranx.com/Search?q=oh+人+之+天&context=古兰经

有人能告诉我如何更改以下代码，以显示每个匹配结果的文本片段吗？我试着阅读了一些例子等，但只能找到新版本的Lucene for Java的相关信息。Lucene对我来说似乎是一个神奇的黑匣子

public static IEnumerable<SearchResult> Search(
    string queryString, 
    out int totalResults,
    int maxResults = 100)
{
    totalResults = 0;
    if (string.IsNullOrEmpty(queryString))
        return new List<SearchResult>();
    var query = new MultiFieldQueryParser(
        Lucene.Net.Util.Version.LUCENE_30,
        new string[] { "Body", "SecondaryReferences" },
        Analyzer
    ).Parse(queryString);
    var indexReader = DirectoryReader.Open(
        directory: Index,
        readOnly: true);
    var indexSearcher = new IndexSearcher(indexReader);
    var resultsCollector = TopScoreDocCollector.Create(
        numHits: maxResults,
        docsScoredInOrder: true
    );
    indexSearcher.Search(
        query: query,
        results: resultsCollector
    );
    totalResults = resultsCollector.TotalHits;
    var result = new List<SearchResult>();
    foreach (var scoreDoc in resultsCollector.TopDocs().ScoreDocs)
    {
        var snippets = new List<SearchResultSnippet>();
        var doc = indexSearcher.Doc(scoreDoc.Doc);
        var searchResult = new SearchResult(
            type: doc.Get("Type"),
            id: doc.Get("ID"),
            snippets: snippets
        );
        result.Add(searchResult);
    }
    return result;
}
