以下是我的收藏结构,有3个收藏,图片,类别和标签
我想过滤所有"图片"它有关键字(FULLTEXT搜索),如" cow"属于"动物"类别并标记为"照片"
如何使用ArangoDB进行此过滤,我使用的是nodejs / foxx。请帮忙。
image{
filename:"myphoto.jpg",
filepath:"/opt/data/949b3e6194bf6f0ef3eb367a615826f8"
categories:[category/6401, category/6402],
tags:[tags/1002],
keywords:"photo green cow"
}
category{
_id:'category/6401',
name:"animals"
}
category{
_id:'category/6402',
name:"living things"
}
tags{
_id:'tags/1002',
name:"photo"
}
tags{
_id:'tags/1003',
name:"colors"
}
答案 0 :(得分:1)
这是一个请求:
FOR i IN FULLTEXT(image, "keywords", "cow") // First search for fulltext
FOR cat IN category // Then Loop on all categories
FILTER cat.name == "animals" // Filter by name
FILTER POSITION(i.categories, cat._id) == true // Join
FOR tag IN tags // Then Loop on all tags
FILTER tag.name == "photo" // Filter by name
FILTER POSITION(i.tags, tag._id) == true // Join
RETURN i // Return all images found
您必须为image.keywords字段设置全文索引
