I am trying to sort on the '\_explanation' field returned from my search query. Elasticsearch is not finding the field and is sorting on infinity instead. I was wondering if there is a solution for this?

results = es.search(index="index", size=50, body={'explain':True,'query': {"function\_score": {  
"query": {  
'bool': {'should': [  
{'constant\_score': {'filter': {'multi\_match': {'query': 'hello', "fields":['field1','field2']}}}}]}  
},  
"functions": [{  
"field\_value\_factor": {  
"field": "field3",  
"factor": 1  
}  
},  
{"field\_value\_factor": {  
"field": "field4",  
"factor": 1  
}}  
],  
"score\_mode": "sum",  
"boost\_mode": "replace"  
}  
},

```
                                           'sort': [{'_explanation.value':{"order":"desc","unmapped_type":"float"}}]
                                           , "track_scores":True})
```
