實作全文檢索搜尋

全文檢索搜尋可用於 SQL Server 的每個執行個體，在 SMO 中是由 FullTextService 物件表示。FullTextService 物件位於 Server 物件之下，可用於管理 Microsoft 全文檢索搜尋服務的組態選項。FullTextCatalogCollection 物件屬於 Database 物件，且為 FullTextCatalog 物件的集合 (這些物件表示針對資料庫所定義的全文檢索目錄)。與一般索引不同的是，您只能為每個資料表定義一個全文檢索索引，這是由 Table 物件中的 FullTextIndexColumn 物件表示。

若要建立全文檢索搜尋服務，您必須在資料庫上定義全文檢索目錄，並在資料庫的其中一個資料表上定義全文檢索搜尋索引。

首先，請呼叫 FullTextCatalog 建構函式並指定目錄名稱，以在資料庫上建立全文檢索目錄。接著再呼叫建構函式，並指定要在其上建立全文檢索索引的資料表，以建立全文檢索索引。接下來可以使用 FullTextIndexColumn 物件並且提供資料表內資料行的名稱，以加入全文檢索索引的索引資料行。然後再將 CatalogName 屬性設定為已建立的目錄。最後呼叫 Create 方法，並在 SQL Server 執行個體上建立全文檢索索引。

範例

如果要使用所提供的任何程式碼範例，您必須選擇建立應用程式用的程式設計環境、程式設計範本，及程式設計語言。如需詳細資訊，請參閱＜如何：在 Visual Studio .NET 中建立 Visual Basic SMO 專案＞或＜如何：在 Visual Studio .NET 中建立 Visual C# SMO 專案＞。

在 Visual Basic 中建立全文檢索搜尋服務

此程式碼範例會針對 AdventureWorks2008R2 範例資料庫中的 ProductCategory 資料表建立全文檢索搜尋目錄。然後在 ProductCategory 資料表的 Name 資料行上建立全文檢索搜尋索引。全文檢索搜尋索引需要資料行上已定義了唯一索引。
