No success to create parent - child relation

Elastic Stack Elasticsearch

Hi folks,

I've been trying to create a simple parent - child relation between
different search types and finally gave up. I'll be happy if you guys
give me a hand on this;

I have 2 types of search documents, simply "package" and "module" as
in programming. Let's talk on the most famous web framework "Django"
package in Python. First, the mappings:

curl -XGET localhost:9200/pydoc/package/_mapping

{"package":{"_source":{"compress":true},"_id":
{"path":"package_name"},"properties":{"summary":{"store":"yes","boost":
1.2,"type":"string"},"keywords":
{"index_name":"tag","store":"yes","boost":
1.4,"type":"string"},"description":{"boost":
0.8,"type":"string"},"package_name":{"store":"yes","boost":
1.8,"type":"string"},"downloads":
{"store":"yes","type":"integer"},"version":
{"index":"not_analyzed","store":"yes","type":"string"}}}}

curl -XGET localhost:9200/pydoc/module/_mapping

{"module":{"_source":{"compress":true},"_routing":
{"required":true},"properties":{"source_code":
{"path":"full","type":"attachment","fields":{"source_code":
{"type":"string"},"author":{"type":"string"},"title":
{"type":"string"},"keywords":{"type":"string"},"date":
{"format":"dateOptionalTime","type":"date"},"content_type":
{"type":"string"}}},"file_path":
{"store":"yes","type":"string"},"import_name":{"store":"yes","boost":
1.8,"type":"string"}},"_parent":{"type":"package"}}}

As we can see, _parent is mapping to "package" type. Than, let's put
our package:

curl -XPUT localhost:9200/pydoc/package/Django -d '{"description":

null, "package_name": "Django", "downloads": 83193, "summary": "A high-
level Python Web framework that encourages rapid development and
clean, pragmatic design.", "version": "1.3.1", "keywords": }'

{"ok":true,"_index":"pydoc","_type":"package","_id":"Django","_version":
1}

Now, the problematic process, putting the module that has Django
package as parent:

curl -XPUT localhost:9200/pydoc/module/mytest?parent=Django -d

'{ "import_name" : "django.mytest.etc", "file_path" : "/path/to/
module.py", "source_code" : { "content": "" } }'

{"ok":true,"_index":"pydoc","_type":"module","_id":"mytest","_version":
1}

Right, show me the module document we have just put:

curl -XGET localhost:9200/pydoc/module/mytest

{"_index":"pydoc","_type":"module","_id":"mytest","exists":false}

Exist false? Weird. What if we search?

curl -XGET localhost:9200/pydoc/module/_search?

q=import_name:django.mytest.etc

{"took":2,"timed_out":false,"_shards":{"total":5,"successful":
5,"failed":0},"hits":{"total":1,"max_score":1.75,"hits":
[{"_index":"pydoc","_type":"module","_id":"mytest","_score":1.75,
"_source" : { "import_name" : "django.mytest.etc", "file_path" : "/
path/to/module.py", "source_code" : { "content": "" } }}]}}

No parent, no parent, no parent at all...

The funny thing when I _search in opposite direction with has_child
query:

curl -XGET localhost:9200/pydoc/package/_search -d '{"query" : {

        "has_child": {
                "type": "module",
                "query": {
                  "term": {
                      "import_name" : "django.mytest.etc"
                  }
                }
             }
        }
    }'

gives me the expected result:
{"took":1,"timed_out":false,"_shards":{"total":5,"successful":
5,"failed":0},"hits":{"total":1,"max_score":1.0,"hits":
[{"_index":"pydoc","_type":"package","_id":"Django","_score":1.0,
"_source" : {"description": null, "package_name": "Django",
"downloads": 83193, "summary": "A high-level Python Web framework that
encourages rapid development and clean, pragmatic design.", "version":
"1.3.1", "keywords": }}]}}

I don't understand. How can I get the parent docs from modules?

Cheers.

children are mapped to the same shard as the parent (using the parent as
the routing value). You need to provide the parent value to the get API as
the routing value. i.e.: ?routing=Django

What if we search?

curl -XGET localhost:9200/pydoc/module/_search?

q=import_name:django.mytest.etc

{"took":2,"timed_out":false,"_shards":{"total":5,"successful":
5,"failed":0},"hits":{"total":1,"max_score":1.75,"hits":

You need to explicitly ask for the _parent field to get it back.

        "has_child": {

I got it,

So you are saying that i have to do another query for each children if
i want to display the results based on parents? Because _parent only
gives the id of the parent.. Don't you think that we should be able to
access like;

"result.meta.parent.package_name" or "result.meta.parent.version"?

cheers.

Yea, it would be nice to be able to access the parent in a script or
something, but its not available now.

thanks a lot kimchy and all the elasticsearch community for letting us
to have such a great search platform. and i also want to thank to the
pyes community for their support on python driver.

as of now, pythonistas are able to "search" for any python package, on
elasticsearch of course. give it a try;

gives the id of the parent.. Don't you think that we should be able to
access like;

"result.meta.parent.package_name" or "result.meta.parent.version"?

cheers.

Hi folks,

I've been trying to create a simple parent - child relation between
different search types and finally gave up. I'll be happy if you
guys
give me a hand on this;

I have 2 types of search documents, simply "package" and "module"
as
in programming. Let's talk on the most famous web framework
"Django"
package in Python. First, the mappings:

curl -XGET localhost:9200/pydoc/package/_mapping

{"package":{"_source":{"compress":true},"_id":

{"path":"package_name"},"properties":{"summary":{"store":"yes","boost":

1.2,"type":"string"},"keywords":
{"index_name":"tag","store":"yes","boost":
1.4,"type":"string"},"description":{"boost":
0.8,"type":"string"},"package_name":{"store":"yes","boost":
1.8,"type":"string"},"downloads":
{"store":"yes","type":"integer"},"version":
{"index":"not_analyzed","store":"yes","type":"string"}}}}

curl -XGET localhost:9200/pydoc/module/_mapping

{"module":{"_source":{"compress":true},"_routing":
{"required":true},"properties":{"source_code":
{"path":"full","type":"attachment","fields":{"source_code":
{"type":"string"},"author":{"type":"string"},"title":
{"type":"string"},"keywords":{"type":"string"},"date":
{"format":"dateOptionalTime","type":"date"},"content_type":
{"type":"string"}}},"file_path":

{"store":"yes","type":"string"},"import_name":{"store":"yes","boost":

1.8,"type":"string"}},"_parent":{"type":"package"}}}

As we can see, _parent is mapping to "package" type. Than, let's
put
our package:

curl -XPUT localhost:9200/pydoc/package/Django -d

'{"description":

null, "package_name": "Django", "downloads": 83193, "summary": "A
high-
level Python Web framework that encourages rapid development and
clean, pragmatic design.", "version": "1.3.1", "keywords": }'

{"ok":true,"_index":"pydoc","_type":"package","_id":"Django","_version":

1}

Now, the problematic process, putting the module that has Django
package as parent:

curl -XPUT localhost:9200/pydoc/module/mytest?parent=Django -d

'{ "import_name" : "django.mytest.etc", "file_path" : "/path/to/
module.py", "source_code" : { "content": "" } }'

{"ok":true,"_index":"pydoc","_type":"module","_id":"mytest","_version":

1}

Right, show me the module document we have just put:

curl -XGET localhost:9200/pydoc/module/mytest

{"_index":"pydoc","_type":"module","_id":"mytest","exists":false}

Exist false? Weird.

children are mapped to the same shard as the parent (using the
parent as
the routing value). You need to provide the parent value to the get
API
as
the routing value. i.e.: ?routing=Django

What if we search?

curl -XGET localhost:9200/pydoc/module/_search?

q=import_name:django.mytest.etc

{"took":2,"timed_out":false,"_shards":{"total":5,"successful":
5,"failed":0},"hits":{"total":1,"max_score":1.75,"hits":
[{"_index":"pydoc","_type":"module","_id":"mytest","_score":1.75,
"_source" : { "import_name" : "django.mytest.etc", "file_path" : "/
path/to/module.py", "source_code" : { "content": "" } }}]}}

No parent, no parent, no parent at all...

You need to explicitly ask for the _parent field to get it back.

The funny thing when I _search in opposite direction with has_child
query:

curl -XGET localhost:9200/pydoc/package/_search -d '{"query" : {

        "has_child": {
                "type": "module",
                "query": {
                  "term": {
                      "import_name" : "django.mytest.etc"
                  }
                }
             }
        }
    }'

gives me the expected result:
{"took":1,"timed_out":false,"_shards":{"total":5,"successful":
5,"failed":0},"hits":{"total":1,"max_score":1.0,"hits":
[{"_index":"pydoc","_type":"package","_id":"Django","_score":1.0,
"_source" : {"description": null, "package_name": "Django",
"downloads": 83193, "summary": "A high-level Python Web framework
that
encourages rapid development and clean, pragmatic design.",
"version":
"1.3.1", "keywords": }}]}}

I don't understand. How can I get the parent docs from modules?

Cheers.
