I'm building search for products and variants. One product can have many
nested variants. Example: 1 T-shirt can be in 2 variants, white for 50
euros and green for 60 euros. It's still the same product and should be
displayed once on the results page.
This is my mapping:
{"product" => { "properties" => {"vendor_variants" => {"type" => "nested"}}}}
And this is the query that I'm doing:
"query" => {
"filtered" => {
"query" => {
"match_all" => {}
},
"filter" => {
"bool" => {
"must" => [
{
"terms" => {
"categories" => [122]
}
}
]
}
}
}
},
"facets" => {
"brand" => { "terms" => {"field" => "filter_brand"} },
"price_range" => {
"nested" => "vendor_variants",
"range" => { "field" => "price", "ranges" => [ {"to" => 2000}, {"from" => 2000, "to" => 5000} ]
}
}
}
This query produces 172 results. But the facets for price ranges are
completely wrong. For example it returns that for 20-50 euro range there
are 422 results. I believe it's because it counts every single nested
vendor_variants document. But it's not what I need, I need it to count only
the main product documents.
What is wrong with my query?
