This function is deprecated and should not be used in new code. See Creating Indexes.


  • collection: A mongoc_collection_t.

  • keys: A bson_t.

  • index_opts: A mongoc_index_opt_t.

  • reply: An optional location for a bson_t which will store the server’s reply.

  • error: An optional location for a bson_error_t or NULL.

command_opts may be NULL or a BSON document with additional command options:


This function will request the creation of a new index.

This function will use the createIndexes command. The server’s reply is stored in reply.

If no write concern is provided in command_opts, the collection’s write concern is used.

See mongoc_index_opt_t for options on creating indexes.


Errors are propagated via the error parameter.


Returns true if successful. Returns false and sets error if there are invalid arguments or a server or network error.

reply is always initialized and must be destroyed with bson_destroy(). If the server is running an obsolete version of MongoDB then reply may be empty, though it will still be initialized.
