DEPRECATED

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

DESCRIPTION

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.


EXAMPLE

{

bson_t keys;
bson_error_t error;
mongoc_index_opt_t opt;
mongoc_index_opt_geo_t geo_opt;
mongoc_index_opt_init (&opt);
mongoc_index_opt_geo_init (&geo_opt);
bson_init (&keys);
BSON_APPEND_UTF8 (&keys, "location", "2d");
geo_opt.twod_location_min = -123;
geo_opt.twod_location_max = +123;
geo_opt.twod_bits_precision = 30;
opt.geo_options = &geo_opt;
collection = mongoc_client_get_collection (client, "test", "geo_test");
if (mongoc_collection_create_index (collection, &keys, &opt, &error)) {
/* Successfully created the geo index */
}
bson_destroy (&keys);
mongoc_collection_destroy (&collection); }
