I am working on indexing emails and have stored the data as

indexing as follows:
doc.add(new Field("date", (String)
itemContent.get("date").toString(), Field.Store.YES,
Field.Index.UN_TOKENIZED));
does this look like a good approach to you all?
Using milliseconds as your resolutions will make range searches very
slow, since it has to enumerate so many values. I suggest using at
most minutes instead.
But either way I suggest using DateTools rather than using a Date
object's toString() form, i.e.:
doc.add(new Field("date",
DateTools.dateToString(itemContent.get("date"),
DateTools.Resolution.MILLISECOND), Field.Store.YES,
Field.Index.UN_TOKENIZED));

I guess the more I think about it I don't really care about the
minutes in the initial. All that matters is the date (i.e.
2006-07-25). The only thing I would need the time for would be for
sorting so I need to have that too. Ideas?
Thanks!

On this note....I want do a RangeQuery on the date (but I only care
about YYYYMMDD). What's the best way to index that? I plan on storing
the timestamp for sorting only.
Thanks.
