大型實體框架查詢，如何預生成或預編譯此查詢

我有一個大的Linq到實體查詢，並且將該linq查詢轉換爲SQL似乎很長。大型實體框架查詢，如何預生成或預編譯此查詢

如何預編譯此查詢。有沒有辦法做到這一點？

這裏是我的查詢。

var ListLocation = from s in repLocation.GetLocationByPermision() 
            .Where(p => (ViewModel.BaseSearchViewModel.IsActive == -1 || p.IsActive == bIsActive) && 
                (ViewModel.LocationTypeID < 0 || ViewModel.LocationTypeID == p.LocationTypeID) && 

                (ViewModel.ListUsageID.Count() == 0 || p.Premises.Select(gs => gs.UsageID).Intersect(ViewModel.ListUsageID).Any()) && 
                (ViewModel.BaseSearchViewModel.City == null || p.Address.City.CityName.Contains(ViewModel.BaseSearchViewModel.City)) && 
                (ViewModel.BaseSearchViewModel.ListCountryID.Count() == 0 || ViewModel.BaseSearchViewModel.ListCountryID.Any(pl => pl == p.Address.City.Province.Country.CtryID)) && 
                (ViewModel.BaseSearchViewModel.ListStateID.Count() == 0 || ViewModel.BaseSearchViewModel.ListStateID.Any(pl => pl == p.Address.City.Province.PrvID)) &&

                 )
