我应该在lucene.net中使用什么分析器来获取URL？

using System;
using Lucene.Net.Analysis;
using Lucene.Net.Documents;
using Lucene.Net.Index;
using Lucene.Net.Store;

public class LuceneIndexer
{
    public static void Main()
    {
        // 创建一个内存中的Directory对象
        RAMDirectory directory = new RAMDirectory();

        // 创建一个IndexWriter对象
        Analyzer analyzer = new StandardAnalyzer(Lucene.Net.Util.Version.LUCENE_48);
        IndexWriter indexWriter = new IndexWriter(directory, analyzer);

        // 创建一个Document对象
        Document doc = new Document();

        // 添加一个字段
        string url = "https://www.example.com/some/path?query=value";
        doc.Add(new Field("url", url, Field.Store.YES, Field.Index.ANALYZED));

        // 将Document对象写入索引
        indexWriter.AddDocument(doc);

        // 提交更改并关闭IndexWriter
        indexWriter.Commit();
        indexWriter.Dispose();

        // 创建一个IndexReader对象
        IndexReader indexReader = DirectoryReader.Open(directory);

        // 创建一个IndexSearcher对象
        IndexSearcher indexSearcher = new IndexSearcher(indexReader);

        // 创建一个查询对象
        QueryParser queryParser = new QueryParser(Lucene.Net.Util.Version.LUCENE_48, "url", analyzer);
        Query query = queryParser.Parse("example");

        // 搜索并打印结果
        TopDocs topDocs = indexSearcher.Search(query, 10);
        foreach (ScoreDoc scoreDoc in topDocs.ScoreDocs)
        {
            Document resultDoc = indexSearcher.Doc(scoreDoc.Doc);
            Console.WriteLine("URL: " + resultDoc.Get("url"));
        }

        // 关闭IndexReader
        indexReader.Dispose();
        directory.Dispose();
    }
}
