I have a simple music catalog:

CREATE TABLE [dbo].[Catalog](
       [CatalogId] [int] IDENTITY(1,1) NOT NULL,
       [Artist] [nvarchar](256) NULL,
       [Title] [nvarchar](256) NULL,
       [Remix] [nvarchar](256) NULL,
       [Album] [nvarchar](256) NULL,
       [Label] [nvarchar](256) NULL,
       [DateAdded] [datetime] NULL CONSTRAINT [DF_Catalog_DateAdded]
DEFAULT (getdate()),
CONSTRAINT [PK_Catalog] PRIMARY KEY CLUSTERED
(
       [CatalogId] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF,
IGNORE_DUP_KEY
= OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

The Full Text index is set on Artist and Title. I wrote the following
Query:

CREATE PROCEDURE [dbo].[CatalogSelectBySearch]
(
       @Artist nvarchar(256),
       @Title nvarchar(256)
)
AS
       SET NOCOUNT ON;

DECLARE                 @SearchTerms nvarchar(512);
SET                             @SearchTerms = '("' + @Artist + '") OR
("' + @Title + '")'

SELECT                  C.CatalogId, C.Artist, C.Title, C.Remix,
C.Album, C.Label,
C.DateAdded
FROM                    dbo.Catalog AS C
INNER JOIN              FREETEXTTABLE(dbo.Catalog, (Artist, Title),
@SearchTerms)
AS KEY_TBL
                               ON C.CatalogId = KEY_TBL.[KEY]
                               ORDER BY KEY_TBL.RANK DESC;

I have a feeling that this query can be done better but I am fairly
new to Full-text and don't know where to start. I tried using
CONTAINSTABLE but when I did that the search was very restrictive. For
instance, if the artist is "Shawn Christoper" in the database and
someone typed "Sean Christoper" to search, no results would come up
using the query structure above. FREETEXTTABLE returns is but the
query is very loose and returns alot of irrelevant results.

Please let me know how I can optimize this query.

Thanks
