Elasticsearch ordering by field value which is not in the filter - sorting

Question

can somebody help me please to make a query which will order result items according some field value if this field is not part of query in request. I have a query:
{
"_source": [
"ico",
"name",
"city",
"status"
],
"sort": {
"_score": "desc",
"status": "asc"
},
"size": 20,
"query": {
"bool": {
"should": [
{
"match": {
"normalized": {
"query": "idona",
"analyzer": "standard",
"boost": 3
}
}
},
{
"term": {
"normalized2": {
"value": "idona",
"boost": 2
}
}
},
{
"match": {
"normalized": "idona"
}
}
]
}
}
}
The result is sorted according field status alphabetically ascending. Status contains few values like [active, canceled, old....] and I need something like boosting for every possible values in query. E.g. active boost 5, canceled boost 4, old boost 3 ........... Is it possible to do it? Thanks.

You would need a custom sort using script to achieve what you want.
I've just made use of generic match_all query for my query, you can probably go ahead and add your query logic there, but the solution that you are looking for is in the sort section of the below query.
Make sure that status is a keyword type
Custom Sorting Based on Values
POST <your_index_name>/_search
{
"query":{
"match_all":{
}
},
"sort":[
{ "_score": "desc" },
{
"_script":{
"type":"number",
"script":{
"lang":"painless",
"inline":"if(params.scores.containsKey(doc['status'].value)) { return params.scores[doc['status'].value];} return 100000;",
"params":{
"scores":{
"active":5,
"old":4,
"cancelled":3
}
}
},
"order":"desc"
}
}
]
}
In the above query, go ahead and add the values in the scores section of the query. For e.g. if your value is new and you want it to be at say value 2, then your scores would be in the below:
{
"scores":{
"active":5,
"old":4,
"cancelled":3,
"new":6
}
}
So basically the documents would first get sorted by _score and then on that sorted documents, the script sort would be executed.
Note that the script sort is desc by nature as I understand that you would want to show active documents at the top, followed by other values. Feel free to play around with it.
Hope this helps!
