Config

There are 2 options for Eve-Elastic taken from app.config:

Query params

Eve-Elastic supports eve like queries via where param which work as term filter.

On top of this, there is a predefined query_string query which does fulltext search.

$ curl http://localhost:5000/items?q=foo&df=name

• q - query (default: *)

• df - default field (default: _all)

Filtering

For more sophisticated filtering, you can use filter query param which will be used as filter for the query, using elastic filter dsl.

Facets

To add a facets support for specific resource, add facets into its datasource:

DOMAIN = {
    'contacts': {
        'datasource':
            'facets': {
                'urgency': {'terms': {'field': 'urgency'}},
                'versioncreated': {'date_histogram': {'field': 'versioncreated', 'interval': 'hour'}}
            }
        }
    }

You will find more info about facets in elasticsearch docs.
