索引

Indexes provide high performance read operations for frequently used queries. Indexes are particularly useful where the total size of the documents exceeds the amount of available RAM.

For basic concepts and options, see 索引概述. For procedures and operational concerns, see 索引操作. For information on how applications might use indexes, see 索引策略.
