SQL Server全文搜索索引使用情況

Question

我已經創建了一個全文搜索目錄，其中包含此目錄中某個表上的一些索引。如何獲得有關創建的全文搜索索引的使用情況的信息？

Answer 1

檢索用戶掃描爲full text search指數與sys.dm_db_index_usage_stats至今：

SELECT FTSC.name AS CatalogName, 
     T.name AS TableName, 
     C.name AS ColumnName, 
     FTSIU.user_scans, 
     FTSIU.last_user_scan 
FROM sys.fulltext_catalogs AS FTSC 
JOIN sys.fulltext_indexes AS FTSI ON FTSC.fulltext_catalog_id = FTSI.fulltext_catalog_id 
JOIN sys.dm_db_index_usage_stats AS FTSIU ON FTSI.object_id = FTSIU.object_id AND FTSI.unique_index_id = FTSIU.index_id 
JOIN sys.tables AS T ON FTSI.object_id = T.object_id 
JOIN sys.columns AS C ON FTSI.object_id = C.object_id 
    AND FTSI.unique_index_id = C.column_id 
WHERE FTSIU.database_id = DB_ID()
