Subject Re: Date Indexing

Oh, and sorry to miss the sorting question.  Lucene can sort search  
results by String or numeric values.  Field.Keyword(String,Date) can  
only be sorted as a String though.  If you truly want to index and  
sort dates but don't need hours, minutes, seconds, milliseconds, then  
index them as YYYYMMDD and you can then sort them as numerics, which  
is much more resource friendly.
