因此,我试图对mongodb文档中的字段进行一些模糊搜索。例如,如果我说6个要搜索的关键字,
['红色','酥脆','甜','松脆','派','耐用'],我正在搜索一个描述苹果品种的字段,我想返回所有有任何苹果的苹果我要搜索的6个关键字中的4个。您将如何使用MongoDB做到这一点?
这里有两个示例文档仅供参考
{
name: "Golden Delicious",
description: "Golden Delicious is a large, yellowish-green skinned cultivar and very sweet to the taste. It is prone to bruising and shriveling, so it needs careful handling and storage. It is a favorite for salads, apple sauce, and apple butter."
}
{
name: "Jonagold",
description: "Jonagold is a cultivar of apple which was developed in 1953 in New York State Agricultural Experiment Station of Cornell University's College of Agriculture and Life Sciences, a cross between the crisp Golden Delicious and the blush-crimson Jonathan. They form a large sweet fruit with a thin skin. "
}
答案 0 :(得分:0)
因此,在玩了一点之后,我想出了一种使用Regex查找特定数量的比赛的方法。这就是我想出的
db.getCollection('apples').find({
description: {
$regex: '((red|crisp|sweet|crunchy|pie|durable).*?){4}',
$options: 'i'
}
})
