with Spring Data Elasticsearch, but i can't find a way to make Unique Count aggregation by field value.

SearchQuery searchQuery = new NativeSearchQueryBuilder()
            .withIndices("logs-processing-*")
            .addAggregation(terms("procedure_code").field("procedure_code.keyword"))
            .build();

现在无法进行测试，但可以肯定，您应该尝试：.addAggregation（terms（“ procedure_code”）。field（“ keyword”））
