我使用lucene版本3.0.3.0,但我搜索的一些表达式无法正常工作.例如,如果我在"模型"字段上搜索"!Fiesta OR Astra",则仅返回"vauxhallAstra"并且不返回"fordFocus".我的代码如下:

var fordFiesta = new Document();

        fordFiesta.Add(new Field("Id", "1", Field.Store.YES, Field.Index.NOT_ANALYZED));

        fordFiesta.Add(new Field("Make", "Ford", Field.Store.YES, Field.Index.ANALYZED));

        fordFiesta.Add(new Field("Model", "Fiesta", Field.Store.YES, Field.Index.ANALYZED));



        var fordFocus = new Document();

        fordFocus.Add(new Field("Id", "2", Field.Store.YES, Field.Index.NOT_ANALYZED));

        fordFocus.Add(new Field("Make", "Ford", Field.Store.YES, Field.Index.ANALYZED));

        fordFocus.Add(new Field("Model", "Focus", Field.Store.YES, Field.Index.ANALYZED));



        var vauxhallAstra = new Document();

        vauxhallAstra.Add(new Field("Id", "3", Field.Store.YES, Field.Index.NOT_ANALYZED));

        vauxhallAstra.Add(new Field("Make", "Vauxhall", Field.Store.YES, Field.Index.ANALYZED));

        vauxhallAstra.Add(new Field("Model", "Astra", Field.Store.YES, Field.Index.ANALYZED));







        Directory directory = FSDirectory.Open(new DirectoryInfo(Environment.CurrentDirectory + "\\LuceneIndex"));

        Analyzer analyzer = new StandardAnalyzer(Version.LUCENE_30);





        var writer = new IndexWriter(directory, …
