> Severe search performance drop in case of sorting on ID fields. I am using a lucene index
where if I query for documents (500 result set) with sorting on document date field, then
I get a resposne in ~2000 ms. However for the same query with sorting on Document Id field,
then I get a response in ~4500 ms. This drop in search performance is even more severe on
larger index.
> Lucene Index:
> 1. Document count: ~1000,000
> 2. Index size: > 8 GB
> Search Query:
> document_subtype:1.1201
> Lucene Search API:
> topDocs  = indexSearcher.Search (userQuery,  null, m_nMaximumRecordSetSize, sortField
);
