	// contains filtered or unexported fields
}

func NewClient

func NewClient(
	url, index string, tls *tls.Config,
	username, password string,
) *Client

func (*Client) Clone

) ([]common.MapStr, error)

type Connection

type Connection struct {
	URL      string
	Username string
	Password string
	// contains filtered or unexported fields
}

func (*Connection) Bulk

func (conn *Connection) Bulk(
	index, docType string,
	params map[string]string, body []interface{},
) (*QueryResult, error)

Bulk performs many index/delete operations in a single API call. Implements: http://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html

func (*Connection) BulkWith

func (conn *Connection) BulkWith(

func (*Connection) Close

func (conn *Connection) Close() error

func (*Connection) Connect

func (conn *Connection) Connect(timeout time.Duration) error

func (*Connection) CountSearchURI

func (es *Connection) CountSearchURI(
	index string, docType string,
	params map[string]string,
) (int, *CountResults, error)

func (*Connection) CreateIndex

func (es *Connection) CreateIndex(index string, body interface{}) (int, *QueryResult, error)

CreateIndex creates a new index, optionally with settings and mappings passed in the body. Implements: https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-create-index.html

func (*Connection) Delete
