Response filtering, exclude some fields by result

[Nikolay Nikolov]

Hi, how can I do this with Elastica?

curl -XGET 'localhost:9200/_search?pretty&filter_path=hits.hits._source&_source=title' { "hits" : { "hits" : [ { "_source":{"title":"Book #2"} }, { "_source":{"title":"Book #1"} }, { "_source":{"title":"Book #3"} } ] } }

Thanks

Nik

As this looks like a less typical query I would recommend to use the raw query option: http://elastica.io/example/raw-array-query.html

[Nikolay Nikolov]

This was only the example of this what I want to do. Are there function to make this over Elastica?

[ruflin]

Yes, see my link above. If there is no predefined query object, you can always use raw queries to map any possible request for elasticsearch.

[Nikolay Nikolov]

I understand, but when I start to use raw queries, I will not use the Elastica framework, because I can make an curl request by my self.

Is it possible to add this feature in the next version of Elastica? I think many of us will use it, because for example you can search in many fields but you would not to become all of this fields in the response. For my example, I am searching in the description of the job, but I would become only the title of the job as response. In this way I am reducing my response object.

If you use raw queries you still get the response object from elastica.

More then happy to have this in one of the future release of Elastica (Pull requests are welcome ;-) ). I think what is not clear to me yet what the exact feature is here? Is it just additional query params and you left out the search query part above? Can you link to the docs from elasticsearch? Elastica mainly maps "elasticsearch" features and builds proxy functions around it.

[Nikolay Nikolov]

Great to hear this :-)

Yes the feature is to be able to set additional parameters to the search URL:

localhost:9200/_search?&filter_path=hits.hits._source&_source=title

In this way I can say which fields I want to have for the result and this will reduce a bunch of my response object. 

Here is the link to ElasticSearch: https://www.elastic.co/guide/en/elasticsearch/reference/current/common-options.html

Thanks

This is actually already implemented. When you use \Elastica\Search::search(...) you can pass your additional params as options array: http://elastica.io/api/classes/Elastica.Search.html#method_search
