Hi,I have a number of indices that are supposed to maintaining "windows" of indexed content - the last month's work of data, for example.
At the moment, I'm cleaning out old documents with a simple cron job making requests like: <delete><query>date_added:[* TO NOW-30DAYS]</query></delete> I was expecting disk usage to plateau pretty sharply as the number of documents in the index reaches equilibrium. However, the usage keeps on going up, after 30 days, albeit not as quickly, even if I optimise the index. Can anyone offer an explanation for this? Should document deletions followed by optimises have as much of an effect on disk usage as I was expecting? Thanks! James
