Full-text Search Using Freetexttable Failing on Noise Words - SQL Server 2008 R2 Transform Noise Words not working

问题 I am running a full-text search for my site using SQL Server 2008 R2 and freetexttable. I am getting this error when a stop word is entered: Informational: The full-text search condition contained noise word(s). So I did what everyone said to do and turned on the Transform Noise Words so the stop/noise words are ignored and the query can continue. But this changed nothing: sp_configure 'show advanced options', 1; RECONFIGURE; GO sp_configure 'transform noise words', 1; RECONFIGURE; GO I still

Why or How does FREETEXTTABLE give a rank value higher than others

I'm using SQLServer 2008 and if I perform the following query: SELECT * FROM FREETEXTTABLE(SomeTable, Name, 'a name that I know exists') I get the rows back that I would expect, but the rank is always 0. Searching for a solution to this problem, I found this question on the Microsoft ASP.NET forum, and sure enough if I add: ALTER FULLTEXT CATALOG MyCatalog REBUILD I start to get a rank - but only temporarily.
