Re: Bug in Nutch, possibly due to issues-273 and 322

[Meghna Kukreja <om...@gmail.com>]

Hi,

I am trying to use nutch-0.9 and it looks like the bug about a NPE
thrown when the generator creates an empty segment is still present.
Has this bug been fixed in the trunk?

Thanks,
Meghna

Highlight terms in hit Title

[searchfresco <se...@bellsouth.net>]

Hi Nutchers!

I'm just wondering where to look to get search terms bolded in hit title.

Where to start or any patches out there?

Thanks

John
