one way would be to use a nested document structure like:
check:
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-nested-type.html#mapping-nested-type
..
"properties" : {
"type":"nested"
"attributes":{
"key" : {
"index" : "not_analyzed",
"type" : "string"
},
"value" : {
"index":"not_analyzed"
"type" : "string"
}
}
}
...
You may even use multiple fields depending of the type of the value, and if
you know the type of each key to be able to index it properly and do search
upon it
"properties" : {
"type":"nested"
"attributes":{
"key" : {
"index" : "not_analyzed",
"type" : "string"
},
"stringValue" : {
"index":"not_analyzed"
"type" : "string"
},
"numericValue" : {
"type" : "float"
}
}
}
How are you going to update the document? If you chose this way and you
perform updates on a nested document(e.g. add a key value) the whole
document is reindexed
Hope it helps
