Hmm, the documentation for ts_headline claims it does this already:
<function>ts_headline</function> accepts a document along
with a query, and returns one or more ellipsis-separated excerpts from
the document in which terms from the query are highlighted.
However, a quick look at the code suggests this is a lie --- I see no
evidence whatever that there's any smarts for putting in ellipses.
Oleg, Teodor, is there something I missed here? Or do we need to change
the documentation?
regards, tom lane
