> Changing the name of the keyword should not affect the query failures, but it did. Can you reproduce that from scratch and provide a full recreation script as described in [About the Elasticsearch category](https://discuss.elastic.co/t/about-the-elasticsearch-category/21). It will help to better understand what you are doing. Please, try to keep the example as simple as possible. A full reproduction script will help readers to understand, reproduce and if needed fix your problem. > Keyword aggregations are much slower than before (UNSOLVED) `"size": 1000000` This is bad IMO. --- _[View the full topic](https://discuss.elastic.co/t/keyword-term-aggregations-much-slower-after-5-6-6-2-upgrade/129180)._
