Elasticsearch random scoring with filters
I've got a situation, using ES 6.5, where I can either perform a bool or a random_score, but not both at the same time. Here is one of those potential queries:
{
"from": 0,
"size": 50,
"query": {
"function_score": {
"random_score": {
"seed": 10,
"field": "_seq_no"
}
},
"bool": {
"filter": [
{
"terms": {
"primary_category": [
"foobar"
]
}
},
{
"terms": {
"primary_type": [
"barbaz"
]
}
}
]
}
}
}
If I were to remove either the function_score block or the bool block, the query works, but in combination, it does not:
[function_score] malformed query, expected [END_OBJECT] but found [FIELD_NAME]
Am I missing something about the example at: https://www.elastic.co/guide/en/elasticsearch/reference/6.2/query-dsl-function-score-query.html#function-random
All I want to do is "randomly sort" my results in a predictable way which will work across pagination, etc. Really I am just trying to display the filtered results with high variance, as any sort of standard sorting will create patterns in the result which I am trying to avoid.
Any help would be appreciated, and I'll keep tinkering with it.
