Hi all  
i have a json with this format:  
{

"\_source": {  
"m\_header": {  
"m\_playerCarIndex": 2  
},  
"m\_lapData": [  
{  
"m\_currentLapTime": 1.5848066806793213  
},  
{  
"m\_currentLapTime": 1.6660668067933333  
},  
{  
"m\_currentLapTime": 1.56577806793213  
}  
}

Is it possible to make a search of array in m\_lapdata where the position is m\_playerCarIndex ?

in this case m\_playerCarIndex: 2

the output should be:  
{  
"m\_currentLapTime": 1.6660668067933333  
}

the second element of array.

Thanks a lot

You could change the format of your JSON when indexing using a [script processor](https://www.elastic.co/guide/en/elasticsearch/reference/7.6/script-processor.html) and put that part of the document in a dedicated field or remove the other parts of the array.

Maybe you can add some more context and explain what you are after.

Thanks!

Then the script processor sounds like a good way to go to change the format of your JSON to whatever suits you best.
