I am using ES 0.14.3.
I'm trying to set up a parent child relationshpi between types
"entity" and "revision". But search does not appear to be working -
throws a QueryParsingException[[test] [has\_child] Type [revision]
does not have parent mapping];
Below is what I used to reproduce this. Do I have to set up parent/
child mappings somewhere?
e.g.:
# curl -XPOST '[http://localhost:9200/test/entity/1?pretty=true](http://localhost:9200/test/entity/1?pretty=true)' -d '{
> "myid" : "1",
> "mydoctype" : "entity"
> }
> '
> {
> "ok" : true,
> "\_index" : "test",
> "\_type" : "entity",
> "\_id" : "1"
> }
# curl -XPOST '[http://localhost:9200/test/revision/2](http://localhost:9200/test/revision/2)?
parent=1&pretty=true' -d '{
> "myid" : "2",
> "mydoctype" : "revision",
> "myrevhead" : "1"
> }
> '
> {
> "ok" : true,
> "\_index" : "test",
> "\_type" : "revision",
> "\_id" : "2"
> }
# curl -XGET '[http://localhost:9200/test/\_search?pretty=true](http://localhost:9200/test/_search?pretty=true)' -d '{
> "from" : 0,
> "size" : 10,
> "query" : {
> "has\_child" : {
> "type" : "revision",
> "query" : {
> "term" : { "mydoctype" : "revision" }
> }
> }
> }
> }

Yes you do, by creating a mapping. See
