摘要： 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.

摘要： Methods and systems for quickly serving documents are provided. Documents may be served to users, for example, in response to search query inputs. Documents may be individually communicated to a document server individually prior to batching the documents. In such a real-time serving system, serving components may fail. To ensure real-time serving despite the failure, spares are utilized to replace the failing serving components such that the spare can immediately begin receiving documents. The spare can also be synchronized with other serving components to obtain the memory of the failing serving component prior to the failure.
摘要翻译：提供了快速提供文件的方法和系统。可以向用户提供文档，例如响应于搜索查询输入。文件可以在批处理文件之前单独传达给文档服务器。在这样的实时服务系统中，服务组件可能会失败。为了确保即使发生故障，即时提供服务，也可以使用备件来替换出现故障的服务组件，以便备件可以立即开始接收文档。备用还可以与其他服务组件同步，以在故障之前获得故障服务组件的内存。

摘要： Methods and systems for quickly serving documents are provided. Documents may be served to users, for example, in response to search query inputs. Documents may be individually communicated to a document server prior to batching the documents. By individually communicating documents to document servers, the document experiences sub-second latency before it is available to a user. The documents may also be modified individually such that real-time serving is not interrupted.

摘要： Methods and systems for serving documents are provided. Documents may be served to users, for example, in response to search query inputs. Documents may be individually received for serving to users. In order to serve documents, documents are typically indexed. To serve documents in a real-time environment, a data structure is configured to index documents that are received while simultaneously being queried for documents to serve to a user. Documents that have not yet completed the indexing process are not available for serving and, thus, are not queried. Additionally, the data structure includes a memory optimizer such that indexing does not waste memory of the data structure.
