Detailed information about searching,indexing technique

[cl...@student.fsa.ucl.ac.be]

Hello. I'm working in a recent company called Denali 
which is interested by using Lucene. I have been 
looking on the official website in order to get 
information about this but i did'nt found any 
explanation about how (in details) the index is create 
and how the search is being made on it .
 In fact we would like to add two special query:
-one which could find what are the most frequent term 
in a document. 
-one which could find what are the most frequent term 
associated whith anoter term(for example: for a given 
term "lucene", we will find "search","moteur","open 
source",....)
If somebody could indicate where I could find details 
information not on "how to use Lucene" but "How does it 
works in details?(algorithme used,...)", it would be 
nice.
Best regards
Claude Libois

The searching phase is trivial, if you know the basic vector model.
The indexing phase is described on pp 196-199. It is a classic algorithm.

Your queries:
1 - see the archive.
2 - you cannot solve it AFAIK. BTW, you would rather play with the 
entropy than with frequencies.
