I’m exploring different ways to structure my indices. I found an article on the Elasticsearch blog about using nested documents. All else being equal, does this structure impact the speed or other performance/accuracy indicators compared to a more standard structure? ---

Hi @mmaccou, There are some limits in place for use of nested types. There is more details [here in the documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/nested.html#_limits_on_nested_mappings_and_objects). There is a potential for performance issues and mapping explosion if the nested type is not used carefully. I'm not sure which blog you're referencing, but [this one](https://opster.com/guides/elasticsearch/data-architecture/elasticsearch-nested-field-object-field/) does have some discussion around object versus nested types. If you are wanting to compare the performance based on your own data structures the [Search Profiler](https://www.elastic.co/guide/en/kibana/current/xpack-profiler.html) could be useful for evaluating your queries. Hope that helps! ---
