Create a FTS in sql2005 on multile fields in multiple tables

According to MSDN...http://msdn.microsoft.com/en-us/library/ms177652.aspx

table Is the name of the table that has been marked for full-text querying. table or view can be a one-, two-, or three-part database object name. When querying a view, only one full-text indexed base table can be involved. table cannot specify a server name and cannot be used in queries against linked servers.

Since your view has full text indexes on more than one table you will not be allowed to do this.

You could possibly use a union to check both tables in your view.

SELECT {your select columns}
FROM Message AS M
    INNER JOIN FREETEXTTABLE(dbo.Message, {your message columns}, 'Doe') AS KEY_TBL
        ON M.Id = KEY_TBL.[KEY]
    INNER JOIN MessageRecipient MR on M.Id = MR.MessageId AND MR.RecipientTypeId=1

Union

SELECT {your select columns}
FROM Message AS M
    INNER JOIN MessageRecipients MR on  M.Id = MR.MessageId AND MR.RecipientTypeId=1
    INNER JOIN FREETEXTTABLE(MR.MessageRecipients, {your MessageRecipients columns}, 'Doe') AS KEY_TBL
        ON MR.Id = KEY_TBL.[KEY];

I don't have access to a SQL installation right now, but let me know if it works.

Just asked a Microsoft Certified Trainer during a developer course for SQL Server. He suggested using a single catalog, and having the two indexes, "title" and "body" in the same catalog.

The only thing to watch is with too many indexes in the same catalog, there is a greater chance for fragmentation within the catalog. With two columns though, this should not be a concern.
