SQL Search :: Can't Get Expected Results With Contains And Full Text Search?

I am using Sql Server 2014 Express edition.I have a table with a varchar(max) column. I have created a full text search that use the stoplist "system". column has this struct: xxx.yyy.zzz.... where xxx, yyy, zzz... are numbers, like 123.345.123123.366456...I can have rows like that:

123.345
123.345
123.345.444
123.345.555
123.345.666
123.345.444.777
123.345.444.888
123.345.555.999

I am trying this query:

select * from Mytable where
contains(MyColumn, '123.345.')

I gues the contains would return all the rows with column contains 123.345, but this does not return all the expected rows, only one row.I have tried to replace "." with "-" but the result is the same.I have also tried with '123.345.*. In this case I have got more results, but no all the exptected rows.If I use this query:

select * from MyTable where
MyCOlumn like '123.345.%';
