ES|QL query API
editES|QL query API
editReturns search results for an ES|QL (Elasticsearch query language) query.
resp = client.esql.query( query="\n FROM library\n | EVAL year = DATE_TRUNC(1 YEARS, release_date)\n | STATS MAX(page_count) BY year\n | SORT year\n | LIMIT 5\n ", ) print(resp)
const response = await client.esql.query({ query: "\n FROM library\n | EVAL year = DATE_TRUNC(1 YEARS, release_date)\n | STATS MAX(page_count) BY year\n | SORT year\n | LIMIT 5\n ", }); console.log(response);
POST /_query { "query": """ FROM library | EVAL year = DATE_TRUNC(1 YEARS, release_date) | STATS MAX(page_count) BY year | SORT year | LIMIT 5 """ }
