Sometimes, what we want is more control over how the buckets are created. The aggregations that we have looked at so far have dealt with a single type of field. If the given field that we want to slice data from is of the string type, we generally use the terms aggregation. If the field is of the numerical type, we have a few choices, including histogram, range aggregation, and others, to slice the data into different segments.

The following aggregations allow us to create one or more buckets, based on the queries/filters that we choose:

• Filter aggregation
• Filters aggregation

Let's look at them, one by one.
