Are similarity scores computed when using sort?

[Aphinyanaphongs, Yindalon]

I have an search application that is very performance conscious.  I've looked 
through the IndexSearcher code, and haven't been able to clarify whether a 
similarity score is calculated if the results are sorted by some numerical 
field value? Basically, it would be preferable to not incur the computational 
cost of generating a similarity score if it is never used.

Thanks

Re: Dutch Analyzer dictionary format?

Judging from everything you've said, the answer is yes.  I don't use
Dutch Analyzer, so I'm not 100% sure about this, but it sounds easy
enough to try.

Dutch Analyzer dictionary format?

[Twan Kogels]

Hello all,
I'm using lucene to search through a couple of documents to find 
interesting documents. Most documents are in Dutch language. I saw that the 
default snowball stemmer wasn't doing well on text written in a foreign 
language. Lucky i found a Dutch text analyzer in de lucene sandbox project.

I've read the javadoc and found out it needs a stemdictionary. You can load 
this dictionary with the following function:
DutchAnalyzer.setStemDictionary(File f)

The format needs to be a tab separator list (word [tab] stem).
To be sure i do everything correctly i've got a question about the dictonary:
Can i just get:

and convert it to a tab separated list and then "feed" it to the 
setStemDictionary() function?

Kind regards,
Twan Kogels

In the Lucene code, I don't see where the reader speicified when

I am looking at DocumentWriter.invertDocument()
It is closed in a finally clause on line 170, when the TokenStream is 
closed.
