Do you have to use filters in Elasticsearch?
Also, as ElasticSearch doesn’t have to care about scoring for filters, they are faster and can be cached. Therefore, a general rule of thumb is to always use filters unless you need the results to be sorted by relevancy according to the query. If a query is not specified, it defaults to the match_all query.
