Question

我有一个MVC.NET应用程序，它有多个过滤器。我的数据库有很多关于汽车的信息。

我想实现用户可以输入的输入字段 “丰田雅力士1.6汽油”并获得与此相匹配的结果。问题是在后端解析这个。我创建了一种解析方法但涉及用户指定键，例如“make”，“model”。

目前我的网站可以执行以下操作：“make = toyota，model = yaris，engine_size = 1.6，fueltype = Petrol”。如您所见，这对用户来说非常复杂。但我需要这些键来获取后端的值并将它们与正确的查询匹配。

<input class="form-control input-sm" name="filterPageSearchModel.GlobalSearchFilter" data-toggle="popover"  data-html="true" id="PartCarSearchField"
                               data-placement="left" title="Example"
                                data-content="<a id='make' onclick='AppendText(this.id)'>make=</a> audi, 
                        <a id='model' onclick='AppendText(this.id)'> model=</a> a4,
                        <a id='enginesize' onclick='AppendText(this.id)'> enginesize=</a> 1.6, 
                        <a id='ribs' onclick='AppendText(this.id)'> ribs=</a> 7,
                        <a id='teeth' onclick='AppendText(this.id)'> teeth=</a> 9, 
                        <a id='voltage' onclick='AppendText(this.id)'> voltage=</a> 12,
                        <a id='amp' onclick='AppendText(this.id)'> amp=</a> 34 a,
                        <a id='power' onclick='AppendText(this.id)'> power=</a>2.0kw,
                        <a id='fueltype' onclick='AppendText(this.id)'> fueltype=</a>petrol"/>

 public IQueryable<PartMMi>GlobalSearchItems(string SearchValues)
    {
        Dictionary<string,string> ConvertedValues = ValuesConverter(SearchValues);
        AutoPartDataClassesDataContext contextAp = new AutoPartDataClassesDataContext();
        InternalDbDataClassesDataContext Context = new InternalDbDataClassesDataContext();
        List<PartMMi> results = new List<PartMMi>();
        var resultMMi = Context.mmis.AsQueryable();

        foreach (var value in ConvertedValues)
        {
            if (LibraryOfParameters.ContainsKey(value.Key)){
                LibraryOfParameters[value.Key] = value.Value;
            }
        }

        if (LibraryOfParameters["make"].Length>0)
            resultMMi = resultMMi.Where(x => x.car.make.Contains(LibraryOfParameters["make"]));
        if (LibraryOfParameters["model"].Length > 0)
            resultMMi = resultMMi.Where(x => x.car.model.Contains(LibraryOfParameters["model"]));
        if (LibraryOfParameters["enginesize"].Length > 0)
            resultMMi = resultMMi.Where(x => x.car.engine_size == Convert.ToDouble(LibraryOfParameters["enginesize"]));


 private Dictionary<string, string> LibraryOfParameters = new Dictionary<string, string>()
        {
            { "make", ""},
            { "model", ""},
            { "enginesize", ""},
            { "ribs", ""},
            { "teeth", ""},
            { "voltage", ""},
            { "amp", ""},
            { "power", ""},
            {"fueltype","" }
        };

public Dictionary<string,string> ValuesConverter(string OriginalSearchValues)
    {
        List<string> splitSearchString = OriginalSearchValues.Split(',').ToList();

        Dictionary<string, string> SearchParameters = new Dictionary<string, string>();

        foreach (string item in splitSearchString)
        {
            string temp1 = item.Split('=').FirstOrDefault();
            string temp2 = item.Split('=').LastOrDefault();
            SearchParameters.Add(temp1.ToLower().Trim(), temp2.Trim());
        }
        return SearchParameters;
    }
