这代表我的映射:
{
"name": {"type": "string", "include_in_all": true},
"properties": {
"type": "nested",
"properties": {
"name": {"type": "string"},
"value": {"type": "string"}
}
}
如何使用facetted搜索'properties.value'的值?这是一个示例文档:
{
"name": "Testproduct",
"properties": [{
"name": "Color",
"value": "Green"
}, {
"name": "Size",
"value": "M"
}]
}
我想通过“Color”属性构建一个facetted列表(仅限)。所以结果应该是这样的:
Red: 7 times
Green: 5 times
Blue: 1 times
这是我到目前为止所尝试的:
{
"size": 1000,
"query": {
"query_string": {
"query": " ... ",
"default_operator": "AND"
}
},
"facets": {
"resolution": {
"nested": "properties",
"facet_filter": {
"term": {
"name": "Color"
}
},
"terms_stats": {
"key_field": "name",
"value_field": "value"
}
}
}
}
如果我执行此搜索查询,我会收到以下回复:
FacetPhaseExecutionException[Facet [resolution]: value_field [value] isn't a number field, but a string];
我几乎不理解答案,但我不知道我的概念是做错了什么。
答案 0 :(得分:1)
那是因为您使用的是terms_stats
。 term_stats
适用于numbers。您应该使用terms
。请尝试此查询:
{
"size": 1000,
"query": {
"query_string": {
"query": " ... ",
"default_operator": "AND"
}
},
"facets": {
"resolution": {
"nested": "properties",
"facet_filter": {
"term": {
"name": "Color"
}
},
"terms": {
"field": "properties.value"
}
}
}
}
