Term aggregations and filtering values with the Java client

Elastic Stack Elasticsearch
1

Hi all,

According to the documentation online and I quote:

"It is possible to filter the values for which buckets will be created.
This can be done using the include and exclude parameters which are based
on regular expressions."

{
"aggs" : {
"tags" : {
"terms" : {
"field" : "tags",
"include" : ".sport.",
"exclude" : "water_.*"
}
}
}
}

See: http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-aggregations-bucket-terms-aggregation.html

I wonder how the include and exclude parameters can be used with the Java
client.

Currently, I use the AggregationBuilder class to add a terms aggregation
to my query like this.

AggregationBuilder aggregation = AggregationBuilders
.terms(queryTerm)
.field(queryField)
.size(size.or(1))
.order(Terms.Order.term(true));

However, I wonder how to use the "include" as described above using the
Java client.
Any help is greatly appreciated! Thanks

How about this:

AggregationBuilder aggregation = AggregationBuilders

.terms(queryTerm)
.field(queryField)
.size(size)
.order(Terms.Order.term(true))
.include(includeRegex)
.exclude(excludeRegex);

Hope that helps,

Colin
