Example 6 with MinAggregationBuilder

use of org.graylog.shaded.elasticsearch6.org.elasticsearch.search.aggregations.metrics.min.MinAggregationBuilder in project elasticsearch by elastic.

the class GlobalAggregatorTests method testCase.

// Note that `global`'s fancy support for ignoring the query comes from special code in AggregationPhase. We don't test that here.
