【问题描述】：

我在 SQL Server 2012 上创建了全文搜索索引。它工作正常，直到我不得不从 Table 中删除包含在 FullTextSearch 中的列。

然后我尝试删除现有的全文索引和目录，然后重新创建它。但不知何故，在重新创建后，它没有显示任何搜索查询结果（之前的结果即将到来）。

我运行了以下查询以了解全文搜索的状态：

declare @id int
select @id = id FROM sys.sysobjects where [Name] = 'TableName'
select 'TableFullTextBackgroundUpdateIndexOn' as 'Property', objectpropertyex(@id, 'TableFullTextBackgroundUpdateIndexOn') as 'Value'
union select 'TableFullTextChangeTrackingOn', objectpropertyex(@id, 'TableFullTextChangeTrackingOn')
union select 'TableFulltextDocsProcessed', objectpropertyex(@id, 'TableFulltextDocsProcessed') 
union select 'TableFulltextFailCount', objectpropertyex(@id, 'TableFulltextFailCount') 
union select 'TableFulltextItemCount', objectpropertyex(@id, 'TableFulltextItemCount') 
union select 'TableFulltextKeyColumn', objectpropertyex(@id, 'TableFulltextKeyColumn') 
union select 'TableFulltextPendingChanges', objectpropertyex(@id, 'TableFulltextPendingChanges') 
union select 'TableHasActiveFulltextIndex', objectpropertyex(@id, 'TableHasActiveFulltextIndex') 
union select 'TableFulltextPopulateStatus', objectpropertyex(@id, 'TableFulltextPopulateStatus') 

它返回以下结果：

我运行以下查询以删除和重新创建全文搜索目录和索引：

        GO
    EXEC sp_fulltext_database 'enable'
    GO
    DROP FULLTEXT INDEX ON [AT].[TableName]
    GO
    DROP FULLTEXT CATALOG [table_search_catalog];
    GO
    CREATE FULLTEXT CATALOG [table_search_catalog] WITH ACCENT_SENSITIVITY = ON;

    GO
    DECLARE @Const Varchar(150)
    DECLARE @Query1 Varchar(MAX)

    SELECT @Const=TC.CONSTRAINT_NAME
    FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS AS TC
    INNER JOIN
    INFORMATION_SCHEMA.KEY_COLUMN_USAGE AS KU
    ON TC.CONSTRAINT_TYPE = 'PRIMARY KEY' AND
    TC.CONSTRAINT_NAME = KU.CONSTRAINT_NAME
    and ku.table_name='TableName'
    ORDER BY KU.TABLE_NAME, KU.ORDINAL_POSITION;


    SET @Query1 ='CREATE FULLTEXT INDEX ON [AT].[TableName]
     ( 
      UserName
         Language 1033,
      ResumeTitle
         Language 1033,
      Address1 
         Language 1033,
      OtherSNSURL 
         Language 1033,
      LinkedInURL 
         Language 1033,
      FacebookURL 
         Language 1033,
      TwitterURL 
         Language 1033, 
      SkypeID 
         Language 1033, 
      comments 
         Language 1033, 
      CurrentCompany 
         Language 1033, 
      PreviousCompany 
         Language 1033
     ) 
      KEY INDEX '+@Const +'
          ON table_search_catalog
       WITH STOPLIST = SYSTEM, CHANGE_TRACKING AUTO'

    EXEC (@query1)


    GO
    Update [AT].[TableName] SET UserName=UserName;

    GO
    ALTER INDEX ALL ON AT.TableName
    REORGANIZE; 

    GO
    ALTER FULLTEXT INDEX ON [AT].[TableName]
       SET CHANGE_TRACKING MANUAL;

    GO
    ALTER FULLTEXT INDEX ON [AT].[TableName]
       START FULL POPULATION;

    GO
    ALTER FULLTEXT INDEX ON [AT].[TableName]
       START update POPULATION;

    GO
    ALTER FULLTEXT INDEX ON [AT].[TableName]
       SET CHANGE_TRACKING AUTO;

显然，全文搜索索引包含要处理的记录，但一段时间后它保持不变。

请告诉我处理记录通常需要多长时间？ 另外应该怎么做才能立即处理待处理的记录（这个查询会很棒）？

谢谢

【参考方案1】：

实际上 20 分钟后，我运行查询以查看更改并发现所有待处理的记录都已处理。但是仍然需要很长时间才能反映这些变化。

谢谢
