Commerce - find variants with no prices

Vote:

I would like to use Episerver Search & Navigation -- Find -- to search for all variants that does have any prices. I am not sure how to build the correct filter to do this.

Code so far:

var itemsWithNoPrices = _client.Search<VariationContent>()
.Filter(x => x.Prices() ????? ) // <-- how to construct?
.Select(x => x.Code)
.GetResult();

"Prices" are added by default via "nested conventions", and are of type IEnumerable<Price>. When a price exists I can see that the json in Find contains:

"Prices$$nested": [
{
"MinQuantity$$number": 0,
"CustomerPricing": {
"PriceCode$$string": "",
"PriceTypeId": 0,
"$type": "Mediachase.Commerce.Pricing.CustomerPricing, Mediachase.Commerce"
},
"UnitPrice": {
"Currency": {
"CurrencyCode$$string": "USD"
},
"Amount$$number": "316.000000000",
"$type": "Mediachase.Commerce.Money, Mediachase.Commerce"
},

And when no prices exists it looks like this:

"Prices$$nested": [],

How should my filter be constructed? Or phrased differently: how do I build a filter for nested queries as "Prices$$nested"?

The reason I want to use Find and not using traversing is, that the catalog contains more than 200.000 variants and Elastic search is quite fast for this.

Have you tried creating a NestedFilter?

Thanks for answering. Not quite sure what you mean by a nested filter, or maybe it is the same as nested queries you refer to?!

I haven't tried it, but perhaps

.Filter(x => x.Prices(), p => p.Amount > 0 ))

might work

Thanks. I did write similar code to what you suggest.

The code I wrote is following the path Quan Mai suggest:

.Filter(x => !x.Prices().MatchItem(p => p.MatchTypeHierarchy(typeof(Price))))

The thing is, that is "pure" Elasticsearch query, it is possible to test the "array" and not by querying a sub-item.
