```
esGET $INDEX/_search --data '
{
"size": 0,
"aggs": {
"counts": {
"terms": {
"field": "$FIELDTYPE",
"show_term_doc_count_error": true,
"size": 500
}
}
}
}
'
```
For example, for RS ingestion codelists:
```
esGET codelist_v10/_search --data '
{
"size": 0,
"aggs": {
"counts": {
"terms": {
"field": "type",
"size": 500
}
}
}
}
'
```
