passing json data in elasticsearch get request using rest-client ruby gem

Question

How do I execute the below query(given in doc) using rest client.

curl -XGET 'http://localhost:9200/twitter/tweet/_search' -d '{
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}
'

I tried doing this:

q = '{
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}
'

r = JSON.parse(RestClient.get('http://localhost:9200/twitter/tweet/_search', q))

This threw up an error:

in `process_url_params': undefined method `delete_if' for #<String:0x8b12e18>     (NoMethodError)
    from /home/socialapps/.rvm/gems/ruby-1.9.3-p194/gems/rest-client-1.6.7/lib/restclient/request.rb:40:in `initialize'
    from /home/socialapps/.rvm/gems/ruby-1.9.3-p194/gems/rest-client-1.6.7/lib/restclient/request.rb:33:in `new'
    from /home/socialapps/.rvm/gems/ruby-1.9.3-p194/gems/rest-client-1.6.7/lib/restclient/request.rb:33:in `execute'
    from /home/socialapps/.rvm/gems/ruby-1.9.3-p194/gems/rest-client-1.6.7/lib/restclient.rb:68:in `get'
    from get_check2.rb:12:in `<main>'

When I do the same using RestClient.post, it gives me the right results!. But the elasticsearch doc uses XGET in curl command for the search query and not XPOST. How do I get the RestClient.get method to work?

If there are alternate/better ways of doing this action, please suggest.

RestClient can't send request bodies with GET. You've got two options:

Pass your query as the source URL parameter:

require 'rest_client'
require 'json'

# RestClient.log=STDOUT # Optionally turn on logging

q = '{
    "query" : { "term" : { "user" : "kimchy" } }
}
'
r = JSON.parse \
      RestClient.get( 'http://localhost:9200/twitter/tweet/_search',
                      params: { source: q } )

puts r

...or just use POST.

UPDATE: Fixed incorrect passing of the URL parameter, notice the params Hash.
