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 Xapian 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 Xapian 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 Xapian to have these implemented. Any help, examples would be appreciated. Thank you.
