Hello, Filippo. You need to POST a MetadataEntry object with the request[0]. For example, in DSpace 5.x this works:
$ curl -s -H "accept: application/json" -H "Content-Type: application/json" -X POST "http://server16.iss.it:8080/rest/items/find-by-metadata-field"; -d '{"key": "dc.contributor.author","value": "Petrini"}' Note that the API only returns exact text matches (no wildcard), and you will probably need to specify the language to actually match anything as well: $ curl -s -H "accept: application/json" -H "Content-Type: application/json" -X POST "http://server16.iss.it:8080/rest/items/find-by-metadata-field"; -d '{"key": "dc.contributor.author","value": "Petrini","language": "en_US"}' The language can also be a literal null (without quotes). It all depends on how your metadata is entered into the database.
