Elastic search 2.4 was used previously and now it has been upgraded to 5.6. I am using the below structure to query the result:

{  
"query": {  
"multi\_match": {  
"query": "' . $searchstringmsg . '",  
"type": "most\_fields",  
"fields": [  
"post\_title",  
"post\_content",  
"custom.cat\_name",  
"custom.series\_name",  
"custom.topic\_name",  
"custom.pos\_format",  
"custom.genre\_name",  
"post\_author.display\_name",  
"post\_meta.wps\_subtitle",  
"terms.post\_tag.name"  
],  
"fuzziness": "1"  
}  
},  
"aggs": {  
"top-sites": {  
"terms": {  
"field": "custom.pos\_format"  
},  
"aggs": {  
"top\_tags\_hits": {  
"top\_hits": {}  
}  
}  
}  
}  
}

Issue: I am getting an empty response of aggregations in the response. As shared like below. Please look in to it.

"aggregations": {  
"top-sites": {  
"buckets": ,  
"sum\_other\_doc\_count": 0,  
"doc\_count\_error\_upper\_bound": 0  
}  
}
