    Abstract: Methods and systems are provided for using a hybrid-distribution system to identify relevant documents based on a search query. A group of documents is assigned to a particular segment. The group of documents is indexed both by atom and by document to form a reverse index and a forward index. Both indexes are divided amongst each node in that segment so that each node is responsible for storing and accessing a different portion of both the reverse and forward indexes. The reverse index portion is accessed on each of a first set of nodes to identify a first set of documents that is relevant to a particular search query. Document identifications associated with the first set of documents are used to identify a second set of nodes that access their forward index portions to limit the number of relevant documents to a second set of documents.

    Abstract translation: 提供了使用混合分发系统来基于搜索查询来识别相关文档的方法和系统。 一组文档被分配给特定的段。 文档组由原子和文档索引，以形成反向索引和前向索引。 这两个索引在该段中的每个节点之间划分，使得每个节点负责存储和访问反向索引和前向索引的不同部分。 在第一组节点中的每一个上访问反向索引部分，以标识与特定搜索查询相关的第一组文档。 与第一组文档相关联的文档标识用于标识访问其前向索引部分的第二组节点，以将相关文档的数量限制为第二组文档。
