    摘要: An apparatus, system, and method are disclosed for updating database indexes on complex data types. Instead of deleting all the index keys for an old indexable entity, only the old index keys which are not in the set of new index keys associated with a replacement indexable entity will be deleted. In addition, only new index keys which are not in the set of old index keys are inserted into the index. In this manner, performance is greatly improved by elimination unnecessary deletions and insertions to an index.
