无塞子的Lucene索引搜索

Question

public IEnumerable<TesisIndx> Search(string searchTerm)
{
        List<TesisIndx> results = new List<TesisIndx>();

        IndexSearcher searcher = new IndexSearcher(FSDirectory.GetDirectory(indexPath));
        QueryParser parser = new QueryParser("Rubro", analyzer);


        PhraseQuery q = new PhraseQuery();
        String[] words = searchTerm.Split(' ');

        foreach (string word in words)
        {
            q.Add(new Term("Rubro", word));
        }

        //Query query = parser.Parse(searchTerm);
        Hits hitsFound = searcher.Search(q);

        TesisIndx sampleDataFileRow = null;

        for (int i = 0; i < hitsFound.Length(); i++)
        {
            sampleDataFileRow = new TesisIndx();
            Document doc = hitsFound.Doc(i);
            sampleDataFileRow.Ius = int.Parse(doc.Get("Ius"));
            sampleDataFileRow.Rubro = doc.Get("Rubro");
            sampleDataFileRow.Texto = doc.Get("Texto");


            results.Add(sampleDataFileRow);
        }
}

Answer 1

它是一个停顿词。然而，当涉及到短语查询时，这并不意味着它根本不被考虑。如果您尝试在解析后打印查询，您应该看到如下内容：

鲁布罗：“？相反的感觉”

该问号表示位置增量，在本例中是删除的停止字。所以它在寻找一个有空隙的短语，在这个空隙中，一个停止词在开头被删除了。
