Tsearch2 headline usage

Hi There,

We are using tsearch2 for FTS implementation. For highlighting the search
term
in the result we are displaying the output of headline function which is
supposed to tag (mark up) those stemmed words in the text that match any of
the
stemmed words in search term. The problem is that some initial part of the
text
is being truncated from the headline output. Can anyone please suggest on
how
to overcome this phenomenon.
