It depends on the kind of query. The main problem is the lack of indexes for literal terms. Since all the "objects" in a statement are stored in the same column, we cannot have specialized indexes for dates, integers, etc. So when doing a search through for a certain date range and other similar stuff, it is doing a manual scan. Also, virtuoso never removes its indexes. It only updates them, cause in the "semantic word" deletions are very rare. > Cheerio, > Ivan > > > -- > Money can't buy happiness, but neither can poverty. > -- Leo Rosten > > _______________________________________________ > Plasma-devel mailing list > Plasma-devel@kde.org > https://mail.kde.org/mailman/listinfo/plasma-devel > > -- Vishesh Handa
