I'm fairly new to full text indexing, my query works as expected, until I search using a phrase containing ' n '.
SELECT C.name FROM dbo.Clients AS C
CONTAINSTABLE (dbo.Clients, name, '"Brick n Clay*"') AS K
ON C.ID = K.[KEY]
Turns out the significance of the ' N ' was that it (along with many other values) exists in the FullTextIndex STOPLIST which aims to prevent searches on meaningless, frequently used values.
One option is to disable the STOPLIST for your table:
ALTER FULLTEXT INDEX ON MyDB.dbo.MyTable SET STOPLIST = OFF
