A solution to search Suffix is given below as its a limitation in FTS that FTS cannot search suffix.
Its not recommended and not efficient as it requires another column but its a solution which can help you out in some cases.
1. Add a column in your table which stores the reverse of the string
SET NewColumnName = REVERSE(ColumnName)
2. CREATE PROCEDURE sps_searchSuffix(@searchString varchar(8000)) AS
SET @searchString = REVERSE(@searchString)
DECLARE @Q nVARCHAR(MAX)
SET @Q = 'SELECT * FROM TableName WHERE CONTAINS (ColumnName,''"'+@searchString+'*"'''+')'
EXEC SP_EXECUTESQL @Q
3. And call it like this if you want to search "garding" and you have a data like "regarding"
DECLARE @ST VARCHAR(500)
SET @ST = 'garding'
EXEC sps_searchSuffix @ST
