I defined matadata by the mapping of the Elasticsearch image Plugin.
Mapping:
"photo" : {
"mappings" : {
"scenery" : {
"properties" : {
"my_img" : {
"type" : "image",
"feature" : {"FCTH" : { }, ... },
"metadata" : {
"jpeg.image_height" : {"type" : "string","store" : true},
"jpeg.image_width" : {"type" : "string","store" : true}
}
}
}
}
}
}
After an index, although searched, metadata does not return.
How do I get a metadata?
I tried:
curl -XPOST 'localhost:9200/photo/scenery/_search' -d '{
"query":{
"image":{
"my_img":{
"feature":"CEDD",
"index":"photo",
"type":"scenery",
"id":"0",
"path":"my_img",
"hash":"BIT_SAMPLING"
}
}
}
}'
Result:
{"took":14,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":5,"max_score":1.0,"hits":[{"_index":"photo","_type":"scenery","_id":"0","_score":1.0, "_source" : {"file_name": "376423.jpg", "my_img": "/9j/4AAQSkZJRgABAQ...
