Elasticsearch Python Interface Partial Update and Update by query
Example
Partial Update: Used when a partial document update is needed to be done, i.e. in the following example the field name of the document with id doc_id is going to be updated to 'John'. Note that if the field is missing, it will just be added to the document.
doc = {
"doc": {
"name": "John"
}
}
es.update(index='index_name',
doc_type='doc_name',
id='doc_id',
body=doc)
Update by query: Used when is needed to update documents that satisfy a condition, i.e. in the following example we update the age of the documents whose name field matches 'John'.
q = {
"script": {
"inline": "ctx._source.age=23",
"lang": "painless"
},
"query": {
"match": {
"name": "John"
}
}
}
es.update_by_query(body=q,
doc_type='doc_name',
index='index_name')
