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);
       }
