Hi,
I have a field 'mysort', I can declare it float, rankfeature...whatever I want.
I use it for index sort:
{
"settings": {
"index": {
"sort.field": "mysort",
"sort.order": "desc"
}
},
And now I want to run a query such that:
"query": {
"function_score": {
"functions": [{ "field_value_factor": { "field": "mysort", "factor": 0.5, "modifier": "ln1p"}} ],
"query": {....}
},
"rescore" : {
"window_size" : 200,
"query" : { "rescore_query" : {... }, "query_weight" : 0.7, "rescore_query_weight" : 1.2 }
}
- use a function_score with field_value_factor and some filters
- the index sort field is used to get top X docs, without touching the rest
- and those are then rescored with a 'rescore' query that is much more complex and slow, with some painless and such.
But I am struggling to find the way, not sure it's possible? As I am not 'sorting' per se, not sure if the index sort would be used if I use function_score??
Any other idea??
thanks
