Entityフレームワークの複雑なクエリのフルテキストインデックス検索

Question

EF 6.0を使用してフルテキストインデックス検索を実行しようとしています。私はIDbCommandInterceptor（http://www.entityframework.info/Home/FullTextSearch）は全文検索を実行する使用していますが、それは私にこの例外がスローされます。それは、フルテキストインデックスが作成できませんので

は列「姓」 にCONTAINSまたはFREETEXT述語を使用することはできません。

LINQクエリ：以下

ListOfEmployees = _context.EmployeeCvs.Include(x => x.Employee) 
.Include(x => x.Tags) 
.Include(x => x.ProjectExperiences) 
.Where(x => x.Employee.FirstName.Contains(SearchQuery.Keyword) || x.Employee.LastName.Contains(SearchQuery.Keyword) || x.ProjectExperiences.Any(y => y.ProjectTitle.Contains(SearchQuery.Keyword) || y.Description.Contains(SearchQuery.Keyword)) || x.Tags.Any(t => t.Title.Contains(SearchQuery.Keyword))) 
.ToList(); 

は、EFによって実行されるクエリです：

私はそれは私に同じエラーを与えているSQL MSでこのクエリを実行しています。

select * from Employee where contains(FirstName,'"John*"') 

このLINQの作品：

var employeeCV = _context.Employees.Where(x => x.FirstName.Contains(SearchQuery.Keyword)).ToList(); 

Answer 1

が含まれていますあなたの問題は、あなたがEmployeesテーブルからではないのフルテキスト実行しようとしているということですが、Extent2上、すなわちSELECT something FROM Employees WHERE ...それがいっぱいではありません - 索引付き。 linqの代わりにT-SQLでlinqのクエリを書き直すか、それを行う必要があります。

（[Var_42]を選択します。[ディスクリミネータ] AS [ID]と[ID]、[Var_42]。[姓] [姓] AS、 [Var_42]。[ディスクリミネータ] [DBO] FROM。私はあなたが試すことを示唆している（[Var_42]。[IsDeleted] = @DynamicFilterParam_IsDeleted_IsDeleted）OR （@DynamicFilterParam_IsDeleted_DynamicFilterIsDisabledがNULLではない）） [Extent2]

---

AS [Var_42] AS [社員] linqクエリを次のように書き換えます：

ListOfEmployees = from cvs in _context.EmployeeCvs.Include(x => x.Employee) 
        where _Context.Employees.Any(
         e=>e.FirstName.Contains(SearchQuery.Keyword) 
         && e.EmployeeID == cvs.EmployeeID 
       )) 

... etc 

これは、正常に動作するはずの簡単なEXISTSステートメントを生成します。 サブクエリに名前を付けることができるため、クエリ構文を使用する方が適しています。

あなたがDynamic filtersを使用しているため、EFがこの "混乱"を起こしている理由があります。

[Var_58]。それだけで生成されたクエリ内の変数@DynamicFilterParam_IsDeleted_DynamicFilterIsDisabledを設定するので、それは、今、あなたを助けにはなりません

_context.DisableAllFilters(); 

を、しかし、クエリ：[IsDeleted] =を使用すると、動的フィルタを無効にしようとした場合

を@DynamicFilterParam_IsDeleted_IsDeleted EntityFramework.DynamicFiltersはEntity Frameworkの一部のメソッドをオーバーライドするため、サブクエリはまだ[Var_xx]です。 this linkを参照してください。

なぜダイナミックフィルタが問題を引き起こすのですか？

理由is mentioned here：

私は（例えば、LINQの .Where（）句を使用して）エンティティクエリの追加フィルタを指定し、これらの追加のフィルタが へのEFは、クエリにサブテーブルを作成する原因となります。

動的フィルタによってサブクエリが作成され、例外が発生する場合はwell described hereになります。同様の回避策はあり推奨されます。 述語が常にに対して実行されるように

（動作しているようです）私は現在使用している回避策は、常に が別々のサブ問合せに本文インデックスの述語を強制することです中間結果セットの代わりに ベーステーブルを使用します。

したがって、フルテキストインデックスを使用しているすべての条件をEXISTSステートメントを区切るために変換しようとする必要があります。

Answer 2

あなたは、データベース内のフルテキストインデックスを作成するために持っているように見え、私は正常にこのようなテーブルの上に直接クエリが含まれているを実行できるにもかかわらず MS SQL Serverを使用している場合は、このリンクhttps://msdn.microsoft.com/en-us/library/ms187317.aspxを参照してください。それ以外の場合は、このリンクを参照してください。https://technet.microsoft.com/en-us/library/aa197912(v=sql.80).aspx - UIでこれを行う場合

持ってる 参加するすべての列がのために有効にフルテキストインデックスが機能

select * from Employee where contains((FirstName,LastName),'"John*"') 
select * from Tag where contains(Title,'"John*"') 

Answer 3

私は問題を解決するために、このようにLINQを書き換えてしまう：

var listOfEmployeeCV = from cvs in _context.EmployeeCvs.Include(x => x.Employee).Include(x=>x.Tags) 
            .Include(x=>x.ProjectExperiences) 
           where _context.Employees.Any(
            e => e.FirstName.Contains(SearchQuery.Keyword) 
            && e.Id == cvs.Employee.Id 
          ) || (_context.Tags.Any(t=>t.Title.Contains(SearchQuery.Keyword) && cvs.Tags.Contains(t))) 
           || (_context.ProjectExperiences.Any(pe=>(pe.ProjectTitle.Contains(SearchQuery.Keyword) 
           || pe.Description.Contains(SearchQuery.Keyword)) && 
           cvs.ProjectExperiences.Contains(pe))) 
           select new 
           EmployeeCvDTO 
           { 
            Employee = new EmployeeDTO 
            { 
             FirstName = cvs.Employee.FirstName, 
             LastName = cvs.Employee.LastName, 
             EnterpriseId = cvs.Employee.EnterpriseId, 
             Level = cvs.Employee.Level 
             //ProfileImageData = x.Employee.ProfileImageData 
            }, 
            Tags = cvs.Tags, 
            ProjectExperiences = cvs.ProjectExperiences, 
           };
