[vi3k6i5]

Support is there on Elasticsearch https://www.elastic.co/guide/en/elasticsearch/reference/1.4/search-request-fields.html

how to do the same with elasticsearch-dsl-py ??

@vi3k6i5

from elasticsearch_dsl import search
search.Search().fields(['fielda', 'fieldb'])

search.Search().partial_fields(foo={
        'include': ['foo.bar.*'],
        'exclude': ['foo.one']
    })

Thanks man. It's not there in the documentation any where. We should add it i guess ?

[apandita]

Its there, look at this doc

http://elasticsearch-dsl.readthedocs.org/en/latest/

and search for this text:

"# fields that should be searched"

@apandita no its not there. The issue i raised is not how to search in a particular field. It's rather how do i specify which fields to be returned in from elasticsearch-dsl. That piece is missing from the documentation.

[apandita]

@Vikash When you pass an array of fields to the search, the result will
always be only those specific fields.

The link i pointed out was not really a direct reference but like a hint to
pick up how to filter fields.

https://github.com/apandita : One question off this topic. I want
elasticsearch-dsl to track_score.
Basically this feature:
https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-sort.html#_track_scores
Any idea how to do that?
PS: let me know if i should be opening another issue for it.
Thanks :)

@apandita : This is what is missing in the document:
search.Search().fields(['fielda', 'fieldb'])
That fields calls. its no where there. I Feel it should be added to the documentation. Let me know how i can help so this gets added to the documentation.
Thanks :)
