Search

GeoNetwork’s legacy Q Search endpoint (/srv/eng/q) has been replaced by an ElasticSearch API. All queries use HTTP POST to:

https://antcat.antarcticanz.govt.nz/geonetwork/srv/api/search/records/_search

The request body is JSON; the response is JSON. The examples below use Python (requests) and curl.

---

Keyword

Search across all fields for a term.

Python

import requests

url = "https://antcat.antarcticanz.govt.nz/geonetwork/srv/api/search/records/_search"

query = {
    "from": 0,
    "size": 10,
    "query": {
        "query_string": {
            "query": "ocean"
        }
    }
}

response = requests.post(url, json=query)
records = response.json()["hits"]["hits"]

curl

curl -X POST "https://antcat.antarcticanz.govt.nz/geonetwork/srv/api/search/records/_search" \
  -H "Content-Type: application/json" \
  -d '{"from":0,"size":10,"query":{"query_string":{"query":"ocean"}}}'

---

Records carrying data

Filter to records that include a data download link.

Python

query = {
    "from": 0,
    "size": 10,
    "query": {
        "query_string": {
            "query": '+linkProtocol:"WWW:DOWNLOAD-1.0-http--download"'
        }
    }
}

response = requests.post(url, json=query)
records = response.json()["hits"]["hits"]

curl

curl -X POST "https://antcat.antarcticanz.govt.nz/geonetwork/srv/api/search/records/_search" \
  -H "Content-Type: application/json" \
  -d '{"from":0,"size":10,"query":{"query_string":{"query":"+linkProtocol:\"WWW:DOWNLOAD-1.0-http--download\""}}}'

---

Keyword + data filter

Combine a text search with the download filter.

Python

query = {
    "from": 0,
    "size": 10,
    "query": {
        "query_string": {
            "query": 'ocean +linkProtocol:"WWW:DOWNLOAD-1.0-http--download"'
        }
    }
}

response = requests.post(url, json=query)
records = response.json()["hits"]["hits"]

curl

curl -X POST "https://antcat.antarcticanz.govt.nz/geonetwork/srv/api/search/records/_search" \
  -H "Content-Type: application/json" \
  -d '{"from":0,"size":10,"query":{"query_string":{"query":"ocean +linkProtocol:\"WWW:DOWNLOAD-1.0-http--download\""}}}'

---

All records

Return all public catalogue records. Increase size or use from to paginate.

Python

query = {
    "from": 0,
    "size": 1000,
    "query": {
        "match_all": {}
    }
}

response = requests.post(url, json=query)
records = response.json()["hits"]["hits"]
total   = response.json()["hits"]["total"]["value"]

curl

curl -X POST "https://antcat.antarcticanz.govt.nz/geonetwork/srv/api/search/records/_search" \
  -H "Content-Type: application/json" \
  -d '{"from":0,"size":1000,"query":{"match_all":{}}}'
