App::ElasticSearch::Utilities::Aggregations - Code to simplify creating and working with Elasticsearch aggregations

=head1 VERSION

version 8.9

=head1 FUNCTIONS

=head2 is_single_stat()

Returns true if an aggregation returns a single value.

=head2 expand_aggregate_string( token )

Takes a simplified aggregation grammar and expands it the full aggregation hash.

Simple Terms:

    field_name

To

    {
        field_name => {
            terms => {
                field => 'field_name',
