I used Lucene to get the first aggregation attempt and set its optimized timid and method through app.config files:
IF (deleditemids == null) deleditemids = new queue (config.rsndexminmerge);
// deleditemids is used to save the DocumentId that needs to be updated
DeletedItemids.enqueue (item.Id);
THIS.RSSINDEXWRITER.ADDDocument (item.getdocument ()); // Indexwriter.
Int doccount = rsSindexwriter.doccount ();
IF (DOCCOUNT% config.rssindexminmergedocs == 0) // Optimize every config.rssindexminmergedocs
{
While (deletedItemids.count> 0)
{// Process for updates
String id = deletedItemids.dequeue () as string;
RSSIndexReader.delete (New Lucene.Net.index.Term (IndexedFeedItem.fn_ItemID, ID));
}
RsSindexReader.close (); // Turn RSSIndexReader.
RsSindexwriter.optimize (); // Perform optimization
Rssindexreader = indexreader.open (config.rsSindexpath); // Reopen RSSIndexReader.
}
