I have an index that when i search for term with out sorting the results are returned in .7
seconds or less. When I choose to search with a column chosen for sorting the results will
return in 7 - 10 seconds. The larger the # of hits the longer it takes when sorting. The
fields that can be sorted on are unique to the document,stored in the index as un_tokenized.
I am using lucene.net 2.0. Index size is normally around 2.5 gig but i have the same problem
on a 500 meg index too. Has anyone else experienced this?
Any help will be greatly appreciated.
Thanks,

I have prepared a test case where TestIndex contains ~200000 docs.
a) making a search and then sorting the (500)results (I used SortedDictionary for sorting)
takes ~140 msec.
b) making a search with Lucene's Sort takes ~6046 msec.
So, there is something to be fixed in Lucene.Net
