Deprecated since version 1.8.0: This structure is deprecated and should not be used in new code. See Manage Collection Indexes.



This structure contains the options that may be used for tuning a specific index.

See the createIndexes documentations in the MongoDB manual for descriptions of individual options.

NOTE:

dropDups is deprecated as of MongoDB version 3.0.0. This option is silently ignored by the server and unique index builds using this option will fail if a duplicate value is detected.
