Note that for MG collections, the total number of partitions generated is a combination of all indexes, sub-collection filters and languages chosen. Two indexes with two sub-collection filters in two languages would yield eight index partitions. For MGPP, all indexes are created in one physical index, so there would only be four index partitions. For Lucene, the number of physical indexes is determined by the number of levels assigned to the collection, one index per level. So for the above situation, one level would result in four physical indexes, while two levels would result in eight.</p> 19 16 20 17 21
