Abstract
Methods, systems, and media are provided for an optimized search engine index. The optimized index is formed by merging small lower level indexes of fresh documents together into a hierarchical cluster of multiple higher level indexes. The optimized index of fresh documents is formed via a single threaded process, while a fresh index serving platform concurrently serves fresh queries. The hierarchy of higher level indexes is formed by merging lower and/or higher level indexes with similar expiration times together. Therefore, as some indexes expire, the remaining un-expired indexes can be re-used and merged with new incoming indexes. The single threaded process provides fast serving of fresh documents, while also providing time to integrate the fresh indexes into a long term primary search engine index, prior to expiring.
