以下は、SQL で where 句を生成していません。

デバッグ時にsearch.Whereパーツが実行されていますが、SQL プロファイラーを調べても表示されません。

using (var db = new CERTContext())
{
    var search = db.Project.Include("ValueStream").Include("Function").AsQueryable();
    if (!lookForDate)
    {
        search.Where(p => p.ProjectName.Contains(searchText) ||
                          p.ProjectDescription.Contains(searchText) ||
                          p.EquipmentName.Contains(searchText) ||
                          p.ValueStream.Description.Contains(searchText) || 
                          p.ValueStream.Description.Contains(searchText) ||
                          p.TrackingId.Contains(searchText) ||
                          p.ENumber.Contains(searchText) ||
                          p.ShamrockNumber.Contains(searchText));

        //.Take(10)
        //.OrderByDescending(p => p.ProjectID);
        //.ToList();
    }
    else
    {// Search on date
        search.Where(p =>
        (System.Data.Objects.EntityFunctions.TruncateTime(p.StartDate) == searchDate));
        //.Take(10)
        //.OrderByDescending(p => p.ProjectID);
        //.ToList();
    }                              
    if (showDeleted != true)
    {
        search.Where(p => p.Deleted == false);
    }
    pList = search.Take(10).OrderByDescending(p => p.ProjectID).ToList();

}// using (var db = new CERTContext())

これは私が得るものです。上位 10 の選択、orderby、joins はありますが、where はありません。

呼び出すだけでWhereは、呼び出したクエリについては何も変わりません。代わりに、現在無視している新しいクエリを返します。あなたがしたい：

search = search.Where(/* code as before */);

編集:次に、宣言を次のように変更する必要もあります。

IQueryable<Project> search = db.Project.(code as before)

AsQueryable(), を使用すると、それが必要ないことを願っていましたが、どうやらそうです。

検索結果を配置します。次のように検索する場所に戻ります。

search = search.Where( // same with your code

クエリから返された結果は失われました。それを検索変数に割り当てる必要があります。
