Elastic

Elastic is an Elasticsearch client for the Go programming language.

Build Status Godoc license

See the wiki for additional information about Elastic.

Releases

Notice that the master branch always refers to the latest version of Elastic. If you want to use stable versions of Elastic, you should use the packages released via gopkg.in.

Here's the version matrix:

Elasticsearch version Elastic version - Package URL
2.x 3.0 gopkg.in/olivere/elastic.v3 (source doc)
1.x 2.0 gopkg.in/olivere/elastic.v2 (source doc)
0.9-1.3 1.0 gopkg.in/olivere/elastic.v1 (source doc)

Example:

You have Elasticsearch 2.0.0 installed and want to use Elastic. As listed above, you should use Elastic 3.0. So you first install Elastic 3.0.

$ go get gopkg.in/olivere/elastic.v3

Then you use it via the following import path:

import "gopkg.in/olivere/elastic.v3"
Elastic 3.0

Elastic 3.0 targets Elasticsearch 2.0 and later. Elasticsearch 2.0.0 was released on 28th October 2015.

Notice that there are a lot of breaking changes in Elasticsearch 2.0 and we used this as an opportunity to clean up and refactor Elastic as well.

Elastic 2.0

Elastic 2.0 targets Elasticsearch 1.x and is published via gopkg.in/olivere/elastic.v2.

Elastic 1.0

Elastic 1.0 is deprecated. You should really update Elasticsearch and Elastic to a recent version.

However, if you cannot update for some reason, don't worry. Version 1.0 is still available. All you need to do is go-get it and change your import path as described above.

Status

We use Elastic in production since 2012. Elastic is stable but the API changes now and then. We strive for API compatibility. However, Elasticsearch sometimes introduces breaking changes and we sometimes have to adapt.

Having said that, there have been no big API changes that required you to rewrite your application big time. More often than not it's renaming APIs and adding/removing features so that Elastic is in sync with Elasticsearch.

Elastic has been used in production with the following Elasticsearch versions: 0.90, 1.0-1.7. Furthermore, we use Travis CI to test Elastic with the most recent versions of Elasticsearch and Go. See the .travis.yml file for the exact matrix and Travis for the results.

Elasticsearch has quite a few features. Most of them are implemented by Elastic. I add features and APIs as required. It's straightforward to implement missing pieces. I'm accepting pull requests :-)

Having said that, I hope you find the project useful.

Getting Started

The first thing you do is to create a Client. The client connects to Elasticsearch on http://127.0.0.1:9200 by default.

You typically create one client for your app. Here's a complete example of creating a client, creating an index, adding a document, executing a search etc.

// Create a client
client, err := elastic.NewClient()
if err != nil {
    // Handle error
}

// Create an index
_, err = client.CreateIndex("twitter").Do()
if err != nil {
    // Handle error
    panic(err)
}

// Add a document to the index
tweet := Tweet{User: "olivere", Message: "Take Five"}
_, err = client.Index().
    Index("twitter").
    Type("tweet").
    Id("1").
    BodyJson(tweet).
    Do()
if err != nil {
    // Handle error
    panic(err)
}

// Search with a term query
termQuery := elastic.NewTermQuery("user", "olivere")
searchResult, err := client.Search().
    Index("twitter").   // search in index "twitter"
    Query(termQuery).   // specify the query
    Sort("user", true). // sort by "user" field, ascending
    From(0).Size(10).   // take documents 0-9
    Pretty(true).       // pretty print request and response JSON
    Do()                // execute
if err != nil {
    // Handle error
    panic(err)
}

// searchResult is of type SearchResult and returns hits, suggestions,
// and all kinds of other information from Elasticsearch.
fmt.Printf("Query took %d milliseconds\n", searchResult.TookInMillis)

// Each is a convenience function that iterates over hits in a search result.
// It makes sure you don't need to check for nil values in the response.
// However, it ignores errors in serialization. If you want full control
// over iterating the hits, see below.
var ttyp Tweet
for _, item := range searchResult.Each(reflect.TypeOf(ttyp)) {
    if t, ok := item.(Tweet); ok {
        fmt.Printf("Tweet by %s: %s\n", t.User, t.Message)
    }
}
// TotalHits is another convenience function that works even when something goes wrong.
fmt.Printf("Found a total of %d tweets\n", searchResult.TotalHits())

// Here's how you iterate through results with full control over each step.
if searchResult.Hits != nil {
    fmt.Printf("Found a total of %d tweets\n", searchResult.Hits.TotalHits)

    // Iterate through results
    for _, hit := range searchResult.Hits.Hits {
        // hit.Index contains the name of the index

        // Deserialize hit.Source into a Tweet (could also be just a map[string]interface{}).
        var t Tweet
        err := json.Unmarshal(*hit.Source, &t)
        if err != nil {
            // Deserialization failed
        }

        // Work with tweet
        fmt.Printf("Tweet by %s: %s\n", t.User, t.Message)
    }
} else {
    // No hits
    fmt.Print("Found no tweets\n")
}

// Delete the index again
_, err = client.DeleteIndex("twitter").Do()
if err != nil {
    // Handle error
    panic(err)
}

Documentation

Overview

Package elastic provides an interface to the Elasticsearch server (http://www.elasticsearch.org/).

The first thing you do is to create a Client. If you have Elasticsearch installed and running with its default settings (i.e. available at http://127.0.0.1:9200), all you need to do is: 

client, err := elastic.NewClient()
if err != nil {
	// Handle error
}

If your Elasticsearch server is running on a different IP and/or port, just provide a URL to NewClient: 

// Create a client and connect to http://192.168.2.10:9201
client, err := elastic.NewClient(elastic.SetURL("http://192.168.2.10:9201"))
if err != nil {
  // Handle error
}

You can pass many more configuration parameters to NewClient. Review the documentation of NewClient for more information.

If no Elasticsearch server is available, services will fail when creating a new request and will return ErrNoClient.

A Client provides services. The services usually come with a variety of methods to prepare the query and a Do function to execute it against the Elasticsearch REST interface and return a response. Here is an example of the IndexExists service that checks if a given index already exists. 

exists, err := client.IndexExists("twitter").Do()
if err != nil {
	// Handle error
}
if !exists {
	// Index does not exist yet.
}

Look up the documentation for Client to get an idea of the services provided and what kinds of responses you get when executing the Do function of a service. Also see the wiki on Github for more details.

Example 
errorlog := log.New(os.Stdout, "APP ", log.LstdFlags)

// Obtain a client. You can provide your own HTTP client here.
client, err := elastic.NewClient(elastic.SetErrorLog(errorlog))
if err != nil {
	// Handle error
	panic(err)
}

// Trace request and response details like this
//client.SetTracer(log.New(os.Stdout, "", 0))

// Ping the Elasticsearch server to get e.g. the version number
info, code, err := client.Ping("http://127.0.0.1:9200").Do()
if err != nil {
	// Handle error
	panic(err)
}
fmt.Printf("Elasticsearch returned with code %d and version %s", code, info.Version.Number)

// Getting the ES version number is quite common, so there's a shortcut
esversion, err := client.ElasticsearchVersion("http://127.0.0.1:9200")
if err != nil {
	// Handle error
	panic(err)
}
fmt.Printf("Elasticsearch version %s", esversion)

// Use the IndexExists service to check if a specified index exists.
exists, err := client.IndexExists("twitter").Do()
if err != nil {
	// Handle error
	panic(err)
}
if !exists {
	// Create a new index.
	createIndex, err := client.CreateIndex("twitter").Do()
	if err != nil {
		// Handle error
		panic(err)
	}
	if !createIndex.Acknowledged {
		// Not acknowledged
	}
}

// Index a tweet (using JSON serialization)
tweet1 := Tweet{User: "olivere", Message: "Take Five", Retweets: 0}

// Index a second tweet (by string)
tweet2 := `{"user" : "olivere", "message" : "It's a Raggy Waltz"}`
put2, err := client.Index().
	Index("twitter").
	Type("tweet").
	Id("2").
	BodyString(tweet2).
	Do()
if err != nil {
	// Handle error
	panic(err)

type Client 

type Client struct {
	// contains filtered or unexported fields
}

Client is an Elasticsearch client. Create one by calling NewClient.

func NewClient 

func NewClient(options ...ClientOptionFunc) (*Client, error)

NewClient creates a new client to work with Elasticsearch.

The caller can configure the new client by passing configuration options to the func.

Example: 

client, err := elastic.NewClient(
  elastic.SetURL("http://127.0.0.1:9200", "http://127.0.0.1:9201"),
  elastic.SetMaxRetries(10),
  elastic.SetBasicAuth("user", "secret"))

If no URL is configured, Elastic uses DefaultURL by default.

If the sniffer is enabled (the default), the new client then sniffes the cluster via the Nodes Info API (see http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/cluster-nodes-info.html#cluster-nodes-info). It uses the URLs specified by the caller. The caller is responsible to only pass a list of URLs of nodes that belong to the same cluster. This sniffing process is run on startup and periodically. Use SnifferInterval to set the interval between two sniffs (default is 15 minutes). In other words: By default, the client will find new nodes in the cluster and remove those that are no longer available every 15 minutes. Disable the sniffer by passing SetSniff(false) to NewClient.

The list of nodes found in the sniffing process will be used to make connections to the REST API of Elasticsearch. These nodes are also periodically checked in a shorter time frame. This process is called a health check. By default, a health check is done every 60 seconds. You can set a shorter or longer interval by SetHealthcheckInterval. Disabling health checks is not recommended, but can be done by SetHealthcheck(false).

Connections are automatically marked as dead or healthy while making requests to Elasticsearch. When a request fails, Elastic will retry up to a maximum number of retries configured with SetMaxRetries. Retries are disabled by default.

If no HttpClient is configured, then http.DefaultClient is used. You can use your own http.Client with some http.Transport for advanced scenarios.

An error is also returned when some configuration option is invalid or the new client cannot sniff the cluster (if enabled).

type Reindexer 

type Reindexer struct {
	// contains filtered or unexported fields
}

Reindexer simplifies the process of reindexing an index. You typically reindex a source index to a target index. However, you can also specify a query that filters out documents from the source index before bulk indexing them into the target index. The caller may also specify a different client for the target, e.g. when copying indices from one Elasticsearch cluster to another.

Internally, the Reindex users a scan and scroll operation on the source index and bulk indexing to push data into the target index.

By default the reindexer fetches the _source, _parent, and _routing attributes from the source index, using the provided CopyToTargetIndex will copy those attributes into the destinationIndex. This behaviour can be overridden by setting the ScanFields and providing a custom ReindexerFunc.

The caller is responsible for setting up and/or clearing the target index before starting the reindex process.

See http://www.elastic.co/guide/en/elasticsearch/guide/current/reindex.html for more information about reindexing.

fmt.Printf("Query took %d milliseconds\n", searchResult.TookInMillis)

// Each is a utility function that iterates over hits in a search result.
// It makes sure you don't need to check for nil values in the response.
// However, it ignores errors in serialization. If you want full control
// over iterating the hits, see below.
var ttyp Tweet
for _, item := range searchResult.Each(reflect.TypeOf(ttyp)) {
	t := item.(Tweet)
	fmt.Printf("Tweet by %s: %s\n", t.User, t.Message)
}
fmt.Printf("Found a total of %d tweets\n", searchResult.TotalHits())

// Here's how you iterate hits with full control.
if searchResult.Hits != nil {
	fmt.Printf("Found a total of %d tweets\n", searchResult.Hits.TotalHits)

	// Iterate through results
	for _, hit := range searchResult.Hits.Hits {
		// hit.Index contains the name of the index

		// Deserialize hit.Source into a Tweet (could also be just a map[string]interface{}).
		var t Tweet
		err := json.Unmarshal(*hit.Source, &t)
		if err != nil {
			// Deserialization failed
		}

		// Work with tweet
		fmt.Printf("Tweet by %s: %s\n", t.User, t.Message)
	}
} else {
	// No hits
	fmt.Print("Found no tweets\n")
}

WildcardQuery matches documents that have fields matching a wildcard expression (not analyzed). Supported wildcards are *, which matches any character sequence (including the empty one), and ?, which matches any single character. Note this query can be slow, as it needs to iterate over many terms. In order to prevent extremely slow wildcard queries, a wildcard term should not start with one of the wildcards * or ?. The wildcard query maps to Lucene WildcardQuery.

For more details, see https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-wildcard-query.html

Example 
// Get a client to the local Elasticsearch instance.
client, err := elastic.NewClient()
if err != nil {
	// Handle error
	panic(err)
}

// Define wildcard query
q := elastic.NewWildcardQuery("user", "oli*er?").Boost(1.2)
searchResult, err := client.Search().
	Index("twitter"). // search in index "twitter"
	Query(q).         // use wildcard query defined above
	Do()              // execute
if err != nil {
	// Handle error
	panic(err)
}
