Index介绍

[英]An index represents how to efficiently store and retrieve data. The common index model allows for easily searching certain fields across all types within an index. The numeric index strategy maps real-world values to insertion keys and query ranges for efficient range scans within a key-value store.
[中]索引表示如何高效地存储和检索数据。通用索引模型允许轻松搜索索引中所有类型的特定字段。数字索引策略将真实值映射到插入键和查询范围，以便在键值存储中进行有效的范围扫描。
