Hi Jack,

I'd like to have more freedom with Nutch... We have two classes,
ParseText and ParseData, which are stored somewhere (I am newbie!) and
then indexed by Lucene. ParseText contains plain text (after parsing by
existing parse-html plugin), and ParseData - links found on a page,
metatags (not sure), etc.

org.apache.nutch.fetcher.Fetch - this class downloads smth using HTTP,
then calls plugin-parser accordingly to "Content" of HTTP header
(text/html in our case)

I'd like to have more freedom, to add more fields to database before
indexing. Probably I can use ParseData.

I'd like to have two-step indexing process, first to index HTML tags and
find similarities (like as usual header, footer, Options, Menu, (c),
etc.), then to use second parsing and second indexing - to index only
unique text.

-Fuad

Waw, Efendi, the features you metioned sounds coool.
Anyway, I hope nutch will both handle DOM tree parsing and information
extraction(Very high level) well one day. My suggestion is adding one
layer between DOM tree parsing and indexing for information extraction.

Comments?
