FragmentDelimiter is an argument for ts_headline function to separates different headline fragments. The default delimiter is " ... ". Currently if someone specifies the delimiter as an option to the function, no extra space is added around the delimiter. However, it does not look good without space around the delimter. Since the option parsing function removes any space around the given value, it is not possible to add any desired space. The attached patch adds space when a FragmentDelimiter is specified. QUERY: SELECT ts_headline('english', ' Day after day, day after day, We stuck, nor breath nor motion, As idle as a painted Ship Upon a painted Ocean. Water, water, every where And all the boards did shrink; Water, water, every where, Nor any drop to drink. S. T. Coleridge (1772-1834) ', to_tsquery('english', 'Coleridge & stuck'), 'MaxFragments=2,FragmentDelimiter=***'); OLD RESULT ts_headline -------------------------------------------- after day, day after day, We <b>stuck</b>, nor breath nor motion, As idle as a painted Ship Upon a painted Ocean. Water, water, every where And all the boards did shrink; Water, water, every where***drop to drink. S. T. <b>Coleridge</b> (1 row) NEW RESULT after the patch ts_headline ---------------------------------------------- after day, day after day, We <b>stuck</b>, nor breath nor motion, As idle as a painted Ship Upon a painted Ocean. Water, water, every where And all the boards did shrink; Water, water, every where *** drop to drink. S. T. <b>Coleridge</b>
