[pylucene-dev] PyLucene Search Result Sorting

[Ram Peters]

I have local site developed using python for my country where people
post classifieds for 7 days for free and pay fees for longer period.
I thinking of using PyLucene to provide searching capabilities.  What
I need to do is:

1. Sort the retrieve data accorinding to newest to oldest based on created_date.
2. Remove expired ads from PyLucene Index periodically every day.
Also if someone post an ad, it should reflect immediately in the
search results.

I am not sure where to start in PyLucene to have these implemented.
Any help, examples would be appreciated.
