使用 LINQ 到 sql 实现字符串单词搜索匹配以搜索每个单词

Question

亲爱的开发者社区，我有以下查询，我正在寻找实现（全词匹配搜索），只是词匹配：

第一次尝试：此代码生成错误（此 LINQ 表达式无法翻译）

fatawaModels = await (
    from f in _dbFactory.GetDataContext.Fatawa
    join ft in _dbFactory.GetDataContext.FatawaTranslation on f.Id equals ft.FatawaId
    let question = ft.FatawaQuestion.Split(" ", StringSplitOptions.None)
    let name = ft.Name.Split(" ", StringSplitOptions.None)
    where ft.LanguageId == GetUserLanguageId().Result &&
    (f.StatusId == (int)Core.DTO.SystemEnum.FatawaStatusId.Approved) &&
    (
        question.Distinct().Intersect(words).Count() == words.Count() ||
        name.Distinct().Intersect(words).Count() == words.Count() 
    )
    select new FatawaModel
    {
        Id = f.Id,
        CreatedBy = f.CreatedBy,
        CreatedDate = f.CreatedDate,
        UpdatedBy = f.UpdatedBy,
        UpdatedDate = f.UpdatedDate,
        Name = ft.Name,
        FatawaQuestion = ft.FatawaQuestion,
        Description = ft.Description,
    }).ToListAsync();

我试试这个：（此代码返回不匹配的单词）

clientSearchText = clientSearchText.Replace(" ", " or ");

fatawaModels = await (
    from f in _dbFactory.GetDataContext.Fatawa
    join ft in _dbFactory.GetDataContext.FatawaTranslation on f.Id equals ft.FatawaId
    where ft.LanguageId == GetUserLanguageId().Result &&
    (f.StatusId == (int)Core.DTO.SystemEnum.FatawaStatusId.Approved) &&
    (
        EF.Functions.Contains(ft.FatawaQuestion, clientSearchText) ||
        EF.Functions.Contains(ft.Name, clientSearchText)
    )
    select new FatawaModel
    {
        Id = f.Id,
        CreatedBy = f.CreatedBy,
        CreatedDate = f.CreatedDate,
        UpdatedBy = f.UpdatedBy,
        UpdatedDate = f.UpdatedDate,
        Name = ft.Name,
        FatawaQuestion = ft.FatawaQuestion,
        Description = ft.Description,
    }).ToListAsync();

因此，请帮助我获得仅匹配单词的预期结果。 谢谢你。
