### 2. Create a sample OPA Policy

In another terminal, create a policy that allows root user all access and for all other users denies `PutObject`:

```sh
cat > example.rego <<EOF
package httpapi.authz

import input

default allow = false

# Allow the root user to perform any action.
allow {
 input.owner == true
}

            boolQuery.filter(query);
        });
        regQ(boolQuery);
        return boolQuery;
    }

    protected TermQueryBuilder regTermQ(String name, Object value) {
        checkEsInvalidQuery(name, value);
        TermQueryBuilder termQuery = QueryBuilders.termQuery(name, value);
        regQ(termQuery);
        return termQuery;
    }

            boolQuery.filter(query);
        });
        regQ(boolQuery);
        return boolQuery;
    }

    protected TermQueryBuilder regTermQ(String name, Object value) {
        checkEsInvalidQuery(name, value);
        TermQueryBuilder termQuery = QueryBuilders.termQuery(name, value);
        regQ(termQuery);
        return termQuery;
    }
