Subject Re: Can I exclude certain terms from MoreLikeThis query?
Date Tue, 25 Aug 2009 06:43:11 GMT
Hi Koji,
Thank you for your reply. Actually, the terms I would like to exclude would
be based on the document I use for MoreLikeThis Query. As I understand
from StopFilter,
it is a static method to exclude terms such as stop words.

My problem is that I want to return theme/area specific results for
MoreLikeThis. Usually, MoreLikeThis picks up nouns such as names and returns
results based on them as it finds them as interesting. I would rather like
it to return results based on general theme of a text. So, I was wondering
if I can prevent MoreLikeThis to exclude results containing a list of
detected nouns that I provide per document.

Thanks,
Paras Chopra
