在我们的Elasticsearch产品系列中,我们有一系列哈希,称为“营养素”。数据的部分示例是:
"_source": {
"quantity": "150.0",
"id": 1001,
"barcode": "7610809001066",
"nutrients": [
{
"per_hundred": "1010.0",
"name_fr": "Énergie",
"per_portion": "758.0",
"name_de": "Energie",
"per_day": "9.0",
"name_it": "Energia",
"name_en": "Energy"
},
{
"per_hundred": "242.0",
"name_fr": "Énergie (kCal)",
"per_portion": "181.0",
"name_de": "Energie (kCal)",
"per_day": "9.0",
"name_it": "Energia (kCal)",
"name_en": "Energy (kCal)"
},
{
"per_hundred": "18.0",
"name_fr": "Matières grasses",
"per_portion": "13.5",
"name_de": "Fett",
"per_day": "19.0",
"name_it": "Grassi",
"name_en": "Fat"
},
在搜索中,我们尝试根据营养素数组中包含的两个字段的完全匹配来恢复产品。我发现的是条件似乎是OR而不是AND。
这两次尝试都是:
"query": {
"bool": {
"must": [
{ "match": { "nutrients.name_fr": "Énergie" } },
{ "match": { "nutrients.per_hundred": "242.0" } }
]
}
}
}
和
"query": {
"filtered": {
"filter": {
"and": [
{ "term": { "nutrients.name_fr": "Énergie" } },
{ "term": { "nutrients.per_hundred": "242.0" } }
]
}
}
}
这两个实际上都带回了Énergie和242.0的条目,但也匹配不同的name_fr,例如:
{
"per_hundred": "242.0",
"name_fr": "Acide folique",
"per_portion": "96.0",
"name_de": "Folsäure",
"per_day": "48.0",
"name_it": "Acido folico",
"name_en": "Folic acid"
},
它们也匹配非完全匹配,即:当我们想要仅匹配“Énergie”时,匹配“Énergie(kCal)”
