I want to ask if the unique field _id be assigned by certain field within
document. I see with Rest, it can achieve by "path":
{
"tweet" : {
"_id" : {
"path" : "post_id"
}
}
}
But if I want to do it with java API, is there any way to achieve it?
Map<String, Object> MapA= new HashMap<String, Object>();
MapA=MapProcessor(MapA);
client.prepareIndex("index","type").setSource(MapA).execute().actionGet();
How could I modify my code to assign certain field in Map to become _id of
this type?
