Instance Method Details
#adapt_response(request, response) ⇒ Object
This method will evaluate the :body value if the params.params == :ruby … otherwise, the body is returned as is. The return object has methods attached, :request and :response. These methods give you access to the original request and response from the connection.
adapt_response
will raise an InvalidRubyResponse if :wt == :ruby and the body couldn’t be evaluated.

arg to form-urlencoded, if the data
arg is a hash. returns a hash with the following keys:

#send_and_receive(path, opts) ⇒ Object
send_and_receive
is the main request method responsible for sending requests to the connection
object.
“path” : A string value that usually represents a solr request handler “opts” : A hash, which can contain the following keys:
:method : required - the http method (:get, :post or :head)
:params : optional - the query string params in hash form
:data : optional - post data -- if a hash is given, it's sent as "application/x-www-form-urlencoded; charset=UTF-8"
:headers : optional - hash of request headers
All other options are passed right along to the connection’s send_and_receive
method (:get, :post, or :head)
send_and_receive
returns either a string or hash on a successful ruby request. When the :params => :ruby, the response will be a hash, else a string.
creates a request context hash, sends it to the connection’s execute
method which returns a simple hash, then passes the request/response into adapt_response
.

#update(opts = {}) ⇒ Object
POST XML messages to /update with optional params.
wiki.apache.org/solr/UpdateXmlMessages#add.2BAC8-update
If not set, opts will be set to a hash with the key ‘Content-Type’ set to ‘text/xml’
opts
can/should contain:
:data - posted data
:headers - http headers
:params - solr query parameter hash
