-free and document oriented

Elasticsearch stores your objects as JSON documents. Most Perl objects
can be mapped easily to their JSON equivalent.

It is schema free, in that you don't need to define 

your
field/properties/attributes ahead of time; you can just toss it a JSON
document and it'll try to autodetect data types and index your doc. That
said, the power of full text search comes from the

    return $self->model->json->encode( $self->search );

The cache_key is a canonical JSON string representation of the full

 deflation or inflation is attempted - the value is passed unaltered. If it
is not a value that L<JSON::XS> can handle (eg a blessed value) then
deflation will fail.

It is mapped as: C<< { type => 'o

An undef value is stored as a JSON C<null>. The mapping and in/deflation depend
on the content type, eg C<Maybe[Int]>.  A C<Maybe> w
