The patch takes into account the corner case of overlap. Here is the
code for that
// start check
if (!startHL && *currentpos >= startpos)
startHL = 1;
The headline generation will not start until currentpos has gone past
startpos.
Ok
You can also check how this headline function is working at my website
indiankanoon.com. Some example queries are murder, freedom of speech,
freedom of press etc.
Looks good.
Should I develop the patch for the current cvs head of postgres?
I'd like to commit your patch, but if it should be:
- for current HEAD
- as extension of existing ts_headline.
