Question about relevance

[Yannick Caillaux <ya...@univ-valenciennes.fr>]

Hi,

I index 2 documents. the first contains the word "Wallis" in the title 
field. The second has the same title but "Wallis" is replaced by "Wall".
I execute the query : "title:wallis"
During the search, "Wallis" is cut by the FrenchAnalyzer and becomes 
"wall". So the two documents are results for the search.

My problem is : the two results have the same relevance.
I thought that the document containing "Wallis" would have better 
relevance because I search for the word "wallis" and not "wall".

Relevance is calculated from the searched word (wallis) or from the 
analyzed word (wall)? Is there any solution to get better relevance for 
the result "wallis" ?
For information i'm in lucene 2.3.2.

Thanks

Yannick

One technique I've seen commonly used is to index both stemmed and  
unstemmed fields, and during search query both and boost the unstemmed  
field matches higher.
