Below is my collection structure, has 3 collection, image, category and tags
I want to filter all "images" which has keyword (FULLTEXT search) like "cow" and belongs to "animals" category and tagged with "photo"
How can I do this filter with ArangoDB, I am using nodejs / foxx . Please help.
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"
}
Here a request :
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
You must have a fulltext index set to your image.keywords field
