Handling Responsesedit
Using the .Aggs
aggregation helper we can fetch our aggregation results easily
in the correct type. Be sure to read more about .Aggs vs .Aggregations
Handling Responsesedit
response.ShouldBeValid(); var filterAgg = response.Aggs.Filter("bethels_projects"); filterAgg.Should().NotBeNull(); filterAgg.DocCount.Should().BeGreaterThan(0); var tags = filterAgg.Terms("project_tags"); tags.Should().NotBeNull(); tags.Buckets.Should().NotBeEmpty();
Empty Filteredit
When the collection of filters is empty or all are conditionless, NEST will serialize them to an empty object.
Fluent DSL exampleedit
s => s .Aggregations(aggs => aggs .Filter("empty_filter", date => date .Filter(f => f .Bool(b => b .Filter(new QueryContainer[0]) ) ) ) )
Object Initializer syntax exampleedit
new SearchRequest<Project> { Aggregations = new FilterAggregation("empty_filter") { Filter = new BoolQuery { Filter = new List<QueryContainer>() } } }
Example json output.
{ "aggs": { "empty_filter": { "filter": {} } } }
Handling Responsesedit
response.ShouldBeValid(); response.Aggs.Filter("empty_filter").DocCount.Should().BeGreaterThan(0);
Inline Script Filteredit
Fluent DSL exampleedit
s => s .Aggregations(aggs => aggs .Filter(_aggName, date => date .Filter(f => f .Script(b => b .Inline(_ctxNumberofCommits) ) ) ) )
Object Initializer syntax exampleedit
new SearchRequest<Project> { Aggregations = new FilterAggregation(_aggName) { Filter = new ScriptQuery { Inline = _ctxNumberofCommits } } }
Example json output.
{ "aggs": { "script_filter": { "filter": { "script": { "script": { "inline": "_source.numberOfCommits > 0" } } } } } }

response.ShouldBeValid(); response.Aggs.Filter(_aggName).DocCount.Should().BeGreaterThan(0);
