我想查詢在.NET上RavenDB嵌入式子元素,文本搜索工作,但WhereBetweenOrEqual,WhereGreaterThan,WhereLessThan不工作如何查詢RavenDB上的子元素?
我的代碼:
public class Document
{
public string Id { set; get; }
public IEnumerable<Attribute> Attributes { set; get; }
}
public class Attribute
{
public string Key { set; get; }
public object Value { set; get; }
}
摘要索引類
public class Document_ByAttribute : AbstractIndexCreationTask<Document>
{
public Document_ByAttribute()
{
Map = documents => from doc in documents
select new
{
_ = doc.Attributes
.Select(attribute =>
CreateField(attribute.Key, attribute.Value, false, true))
};
}
}
This is Working
public ActionResult Filter(string id)
{
var doc = _Session.Advanced.LuceneQuery<Document>("Document/ByAttribute").Search("Title", "*" + id + "*").ToList();
return Json(doc, JsonRequestBehavior.AllowGet);
}
此功能不起作用
public ActionResult Price_Range(decimal min = 0, decimal max = 99999999)
{
var doc = _Session.Advanced.LuceneQuery<Document>("Document/ByAttribute").WhereBetweenOrEqual("Price", min, max).ToList();
return Json(doc, JsonRequestBehavior.AllowGet);
}
我試過了一切。我沒有成功。 請幫幫我。怎麼辦?
在此先感謝。
