== Bucket Aggregations
Bucket aggregations don't calculate metrics over fields like the metrics aggregations do, but instead, they create
buckets of documents. Each bucket is associated with a criterion (depending on the aggregation type) which determines
whether or not a document in the current context "falls" into it. In other words, the buckets effectively define document
sets. In addition to the buckets themselves, the `bucket` aggregations also compute and return the number of documents

that "fell into" each bucket.

Bucket aggregations, as opposed to `metrics` aggregations, can hold sub-aggregations. These sub-aggregations will be
aggregated for the buckets created by their "parent" bucket aggregation.
There are different bucket aggregators, each with a different "bucketing" strategy. Some define a single bucket, some
define fixed number of multiple buckets, and others dynamically create the buckets during the aggregation process.

SignificantText aggregation - like significant_terms, but for text (#24432) * SignificantText aggregation - like significant_terms but doesn’t require fielddata=true, recommended used with `sampler` agg to limit expense of tokenizing docs and takes optional `filter_duplicate_text`:true setting to avoid stats skew from repeated sections of text in search results. Closes #23674
