To retrieve all images of “Paris” the city, first query the API with the term “paris” but some pictures of Paris the city or any other pictures with someone named Paris or containing “paris” in the indexed fields for example could be fetched.
Considering that the field “City” is conscientiously filled, it’s a good idea to restrict the search to this field only: the query can be done by searching terms in a specified list of documentary fields.
To do so, provide an additional “fields” parameter and explicitly ask for the desired fields where to look for.
curl -v -d "oauth_token=xxxxxxx&fields=City&type=image" https://mydomain.tld/api/v1/search/
The “fields” parameter is an array, so one or more fields can be specified.
