Update by query

Updating documents matching a query

Replace the match_all query with any query that you would like.

POST /products/_update_by_query
{
  "script": {
    "source": "ctx._source.in_stock--"
  },
  "query": {
    "match_all": {}
  }
}

Ignoring (counting) version conflicts

The conflicts key may be added as a query parameter instead, i.e. ?conflicts=proceed.

POST /products/_update_by_query
{
  "conflicts": "proceed",
  "script": {
    "source": "ctx._source.in_stock--"
  },
  "query": {
    "match_all": {}
  }
}

Matches all of the documents within the products index

GET /products/_search
{
  "query": {
    "match_all": {}
  }
}
