Nutch 2.2.1: Question about Indexing Structure

[A Laxmi]

Hi,

I am using Nutch 2.2.1 with HBase. I have couple of questions about the
index fields in Nutch:

1. With ref to link below, what is the difference between '*site*' and '
*url*'?
Link [0]: http://wiki.apache.org/nutch/IndexStructure

2. From gora-hbase-mapping.xml - with ref to Link[0] above, '*url*' will be
'*baseUrl*' in hbase (data Nutch stores). What will be '*site*'?


Thanks for any help..
