Well first Lucene checks all of the other documents in the world for any
that that refer to the document that your adding to Lucene...and
then...oh wait...

Hmm..doesn't lucene scoring determine how relevant a document is to your
query? That is what PageRank and HITS do as well, I believe. Page and
document are the same, if you want to index a page you'll obviously
try to
convert it into a document. PageRank does link analysis to determine how
relevant that page is as it relates to the query you entered, does lucene
have something similar? How does lucene determine between two documents
which one should score higher if they both contain a certain term? Google
uses PageRank to make that determination, how does lucene do it?

In fact Lucene is just a search engine. Then you can use the search
engine
to
search in web pages, like Nutch is using Lucene. And Google is more like
Nutch : a web crawler plus a web-search engine. So when you are taking
about
page raking, it has nothing to do with Lucene scoring. Lucene scoring is
how
about the result entry match your query. Page raking is more about how
relevant is the web page. So for a document, the Lucene scoring
depends on
the query, and the page raking is quite absolute.
