tsearch2 match substrings in words

["Muller Zsolt" <mzsolt@xxxxxxxxxx>]

Hi,

Is it possible using tsearch2 to match a substring of an element of a ts_vec 
column?

For example: I have a table with a ts_vec, and I have a field with text, and 
if there is a value in the field "I would like to match the beginning of the 
words" - and the ts_vec has " 'like':3 'match':5 'begin':7 ...etc" then it 
would be cool to create a query, which give me a headline for "begin" if I 
just use the "beg" (or "beg*" ) search expression.

Is there a way to solve this?

Thanks in advance.
