Elasticsearch: remove/update field inside nested object

Question

{
  \"_index\" : \"test\",
  \"_type\" : \"test\",
  \"_id\" : \"1212\",
  \"_version\" : 5,
  \"found\" : true,
  \"_source\" : {
    \"count\" : 42,
    \"list_dat         


        

Answer 1

I don't know why, but I find that

ctx._source.list_data.removeAll{it.list_id == remove_id}

can't work. Instead I use removeIf like this:

ctx._source.list_data.removeIf{list_item -> list_item.list_id == remove_id}

where list_item could be arbitrary string.
