@brief drops an index collection.dropIndex(index)

Drops the index. If the index does not exist, then false is returned. If the index existed and was dropped, then true is returned. Note that you cannot drop some special indexes (e.g. the primary index of a collection or the edge index of an edge collection).

collection.dropIndex(index-handle)

Same as above. Instead of an index an index handle can be given.
