c# - RavenDB 搜索多个单词

Question

我想在 RavenDB 中搜索文档，并使搜索的每个单词的搜索结果更加精确。
这是我当前的代码(简化)。对于循环中的每次迭代，我想创建和“and”子句。这怎么可能？
目前，我只是为每个单词获得更多结果，但我希望每个单词获得更少结果。

using (var session = this.ravenSession.Store.OpenAsyncSession())
{
    var query = session.Query<TestDocument, TestIndex>();

    foreach (string word in search.Split(' '))
    {
        query = query.Search(x => x.Brand, word, boost: 5)
                     .Search(x => x.Model, word, boost: 3)
                     .Search(x => x.Variant, word)
                     .Search(x => x.Color, word);
    }
}

已解决 :我必须使用 DocumentQuery 并为每个循环创建子子句。

using (var session = this.ravenSession.Store.OpenAsyncSession())
{
    var query = session.Advanced.AsyncDocumentQuery<TestDocument>();

    var words = search.Split(' ');

    for (int i = 0; i < words.Length; i++)
    {
        query.OpenSubclause();

        query = query.Search(x => x.Brand, words[i]).Boost(5).OrElse()
                     .Search(x => x.Model, words[i]).Boost(3).OrElse()
                     .Search(x => x.Variant, words[i]).OrElse()
                     .Search(x => x.Color, words[i]);

        query.CloseSubclause();

        if (i < (words.Length - 1))
        {
            query.AndAlso();
        }
    }
}
