Question

我每次在python中使用这个程序来更新elasticsearch上我的数据库的字符串字段。现在我想要将Field的值加倍1000，new_Value= Old_Value*1000 谁能告诉我，我的代码需要改变什么？

from elasticsearch import Elasticsearch
es = Elasticsearch()

index_to_search = 'testindex'
doc_type= 'trends'

Ergebnisse = es.search( index = index_to_search, doc_type = doc_type, size = 100,body = {"query":{"bool":{"must":[{"range":{"Value":{"gt":"0"}}}],"must_not":[],"should":[]}},"from":0,"size":1000,"sort":[]}

)
data = (Ergebnisse ['hits']['hits'] )    
print('Alle Suchergebnisse: ', data)
#print(data['Value'])

for Eintrag in data:
        Sensor = Eintrag
        sensortupel = {"Index": Sensor['_index'],"Value":Sensor['_source']['Value']}
        OldValue= float(sensortupel['Value'])
        print("\nOldValue:", OldValue)
        NewValue = OldValue *1000
        print('NewValue:',NewValue)
        q = {
        "query": {
        "match_all": {}
        },
        "script": {
        "inline": "ctx._source.Value= NewValue",
        # write the name of field and with which new value should be updated  
                }
        }
        result = es.update_by_query(body=q, doc_type=doc_type, index=index_to_search)
        print('Result is : ', result

编辑：

错误在这里：

"inline": "ctx._source.Value={}".format(NewValue), # change it in code above

提供的代码示例不是自包含的，因此我无法对其进行测试。

如果我正确地告诉您，您正试图将ctx._source.Value设为NewValue。

如果您只是将"inline": "ctx._source.Value= NewValue",替换为"inline": "ctx._source.Value={}".format(NewValue),会怎样？

Elasticsearch按查询更新＆＃34;值＆＃34; * 1000使用python
