Lucene development

RE: result sorting code

Hi Morary,

I'm also using Lucene.Net, I have made my own custom sorting which fetches 
the fields of the document on which the sorting is performed from the Hits 
collections. It's a pretty forward (and slow solution), the only 
optimization I can do is use paging information to only sort the number of 
results needed.

I haven't had a look at the sorting solution contributed to the java version 
of Lucene, can you tell me how the sorting is done. I'm interested wether 
there is a another possibility to sort results without fetching the 
individual documents from the index.

I'm looking forward to your .Net port of this code, let me know if you need 
help with it (maybe testing or so).

greetings,

Yussef

Re: result sorting code

that file list looks correct, with the exception of the test cases,
src/test/org/apache/lucene/search/TestSort.java.

the overall structure is pretty finalized, I think.  There's a few
minor changes which could be made to the code - reduce some of the
code duplication in the *SortedHitQueue.java files, use a WeakHashMap
for the cache, etc. - but otherwise I think it's pretty close ...
