I am beginning to use the full text search facilities in Postgresql
(9.0) and find the result of this query a bit strange:

query:

SELECT  ts_headline('simple',title, to_tsquery('kerkreg|(church & polity)'))
from akb_articles A
where A.tsv@@ 'kerkreg|(church & polity)'

Result

"Kerkvereniging en <b>Kerkreg</b>: Geskiedenis, beginsel en praktyk.(<b>Church</b> unity and <b>church</b> polity:
History,principle and practice.)" 

Why is 'polity' not highlighted?

Regards
Johann
