Indexes¶

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 Indexing Overview. For procedures and operational concerns, see Indexing Operations. For information on how applications might use indexes, see Indexing Strategies.
