Melissa:

These questions are answered in the Lucene FAQ, which is located at

http://www.lucene.com/cgi-bin/faq/faqmanager.cgi

However, if I correctly understand your fundamental question, my
understanding is that Lucene basically uses the vector model of IR.

In http://www.lucene.com/publications.html you will find many answers to
your questions. The papers "An Object-Oriented Architecture for Text
Retrieval" and "Optimizations for Dynamic Inverted Index Maintenance"
will be especially helpful for your understanding of Lucene.

Hi again!

I should really reword my question as follows:

On which criteria are relevant documents chosen given a particular query

and

once retrieved, how are these documents ranked?

The techniques by which this is done will then determine what type of IR
model Lucene implements.

Thanks again!

You should read the Lucene FAQ
http://www.lucene.com/cgi-bin/faq/faqmanager.cgi ). Most of your questions
(over the past few days) are already answered there.

Hi again!

I should really reword my question as follows:

On which criteria are relevant documents chosen given a particular query

and

once retrieved, how are these documents ranked?

The techniques by which this is done will then determine what type of IR
model Lucene implements.

Thanks again!

Melissa
