Predicate search returning incorrect HTTP status

[MattBlissett]

https://api.gbif.org/v1/occurrence/search/predicate should return 200, not 201.

curl -X 'POST' \
  'https://api.gbif.org/v1/occurrence/search/predicate' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{
  "predicate": {
    "type": "and",
    "predicates": [
      {
        "type": "equals",
        "key": "COUNTRY",
        "value": "FR"
      },
      {
        "type": "equals",
        "key": "YEAR",
        "value": "2017"
      }
    ]
  }
}'
