I have a simple terms query with a list of IDs defined. My goal is to get results back in the same order as it was defined in the input array. How to achieve that?
{
query: {
terms: {
_id: ["12", "34", "6", "22"]
}
}
}
You can use Script based sorting for same. you can provide sort order and based on it, script will order your response.
POST index/_search
{
"query": {
"terms": {
"id": ["12", "34", "6", "22"]
}
},
"sort": {
"_script": {
"type": "number",
"script": {
"inline": "params.sortOrder.indexOf(doc['id'].value)",
"params": {
"sortOrder": ["12", "34", "6", "22"]
}
},
"order": "asc"
}
}
}
