_source filtering input validation & behavior #19008
Description
_source filtering returns the full contents of the _source when supplied with a number (as opposed to a string). It would be better to return nothing and/or not be valid + throw an error.
Add a document:
PUT myindex/mytype/1
{
"field1": "Hello World!"
}
Pass in a number:
GET myindex/_search
{
"_source": 1
}
The result:
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 1,
"hits": [
{
"_index": "myindex",
"_type": "mytype",
"_id": "1",
"_score": 1,
"_source": {
"field1": "Hello World!"
}
}
]
}
}
