Original install method (e.g. download page, yum, from source, etc.):

for example, this is a kibina visualization json in index .kibana:
//////////////////////////////////////////////////////
{
"_index": ".kibana",
"_type": "visualization",
"_id": "08a67c30-4b43-11e7-8734-a9fa787d77b3",
"_score": 9.687088,
"_source": {
"title": "temp visualization",
"visState": """{"title":"temp visualization","type":"pie","params":{"addTooltip":true,"addLegend":true,"legendPosition":"right","isDonut":false},"aggs":[{"id":"1","enabled":true,"type":"count","schema":"metric","params":{}},{"id":"2","enabled":true,"type":"terms","schema":"segment","params":{"field":"sahab_metadata.source","size":5,"order":"desc","orderBy":"1"}}],"listeners":{}}""",
"uiStateJSON": "{}",
"description": "",
"version": 1,
"kibanaSavedObjectMeta": {
"searchSourceJSON": """{"index":"twitter","query":{"query_string":{"query":"*","analyze_wildcard":true}},"filter":[]}"""
}
}
}
////////////////////////////////////////////////////////////////

now, I need to get the elastic query of above visualization through code and programing.

the desire output is:

{
"query": {
"query_string": {
"query": "*",
"analyze_wildcard": true
}
},
"size": 0,
"_source": {
"excludes": []
},
"aggs": {
"2": {
"terms": {
"field": "sahab_metadata.source",
"size": 5,
"order": {
"_count": "desc"
}
}
}
}
}
