EXPORTS

qs_init()

    use Elasticsearch::Util::API::QS qw(qs_init);
    $handler = qs_init( @qs_params );
    $qs_hash = $handler->($params);

The qs_init() sub accepts a list of query string parameter names, and returns a handler which can extract those parameters from \%params and return a hash of values to be passed as a query string.

For instance:

    $handler = qs_init(qw(fields size from));
    $params  = { fields =>['foo','bar'], size => 10, query=>\%query };
    $qs_hash = $handler->($params);

Would result in:

    $qs_hash: { fields => 'foo,bar', size => 10};
    $params:   { query => \%query }
