Tsearch not searching 'Y'

Hello All,

I am trying to get tsearch working for my application but I am facing a
problem when alphabet 'Y' is the in the tsquery.

can anyone please share some light on it.

# SELECT 'hollywood'::tsvector @@ to_tsquery('holly:*');
?column?
----------
f
(1 row)

SELECT 'hollywood'::tsvector @@ to_tsquery('holl:*');
?column?
----------
t
(1 row)

It works when i put <> in y as below but i don't want to do it that way.

SELECT 'hollywood'::tsvector @@ to_tsquery('holl<y>:*');
?column?
----------
t

Thanks in advance
