Cannot use sort option in conjunction with rescore – How to solve this Elasticsearch exception

Opster Team

August-23, Version: 6.8-6.8

Briefly, this error occurs when you try to use the ‘sort’ option along with ‘rescore’ in the same Elasticsearch query. Elasticsearch does not support this combination because ‘rescore’ re-ranks the top results returned by the query, while ‘sort’ orders all the results, which can lead to inconsistencies. To resolve this issue, you can either remove the ‘sort’ option if ‘rescore’ is more important for your use case, or vice versa. Alternatively, you can perform the sorting operation in your application after retrieving the results from Elasticsearch.
