I'm going to be merging a breaking change shortly. Please contact me directly if you need more than a week to prepare for this. I'm thinking of doing the merge on the 26th of February.
A Go (Golang) based Elasticsearch client, implements core api for Indexing and searching. GoDoc http://godoc.org/github.com/mattbaird/elastigo
To get the Chef based Vagrantfile working, be sure to pull like so::
# This will pull submodules.
git clone --recursive git@github.com:mattbaird/elastigo.git
- 2013-9-27 Fleshing out cluster and indices APIs, updated vagrant image to 0.90.3
- 2013-7-10 Improvements/changes to bulk indexer (includes breaking changes to support TTL),
Search dsl supports And/Or/Not
- SearchDsl should still be considered beta at this point, there will be minor breaking changes as more of the elasticsearch feature set is implemented.
- 2013-1-26 expansion of search dsl for greater coverage
- 2012-12-30 new bulk indexing and search dsl
- 2012-10-12 early in development, not ready for production yet.
examples:
import "github.com/mattbaird/elastigo/api"
import "github.com/mattbaird/elastigo/core"
type Tweet struct {
User string `json:"user"`
Message string `json:"message"`
}
// Set the Elasticsearch Host to Connect to
api.Domain = "localhost"
// api.Port = "9300"
// add single go struct entity
response, _ := core.Index(true, "twitter", "tweet", "1", Tweet{"kimchy", "Search is cool"})
// you have bytes
tw := Tweet{"kimchy", "Search is cool part 2"}
bytesLine, err := json.Marshall(tw)
response, _ := core.Index(true, "twitter", "tweet", "2", bytesLine)
// Bulk Indexing
core.IndexBulk("twitter", "tweet", "3", &time.Now(), Tweet{"kimchy", "Search is now cooler"})
// Search Using Raw json String
searchJson := `{
"query" : {
"term" : { "user" : "kimchy" }
}
}`
out, err := core.SearchRequest(true, "twitter", "tweet", searchJson, "")
if len(out.Hits.Hits) == 1 {
fmt.Println(string(out.Hits.Hits[0].Source))
}
A Faceted, ranged Search using the Search DSL :
import "github.com/mattbaird/elastigo/api"
import "github.com/mattbaird/elastigo/core"
// Set the Elasticsearch Host to Connect to
api.Domain = "localhost"
// api.Port = "9300"
out, err := Search("github").Size("1").Facet(
Facet().Fields("actor").Size("500"),
).Query(
Query().Range(
Range().Field("created_at").From("2012-12-10T15:00:00-08:00").To("2012-12-10T15:10:00-08:00"),
).Search("add"),
).Result()
A Ranged Search using the Search DSL :
out, err := Search("github").Type("Issues").Pretty().Query(
Query().Range(
Range().Field("created_at").From("2012-12-10T15:00:00-08:00").To("2012-12-10T15:10:00-08:00"),
).Search("add"),
).Result()
A Simple Search using the Search DSL :
out, err := Search("github").Type("Issues").Size("100").Search("add").Result()
A Direct Search using the api :
qry := map[string]interface{}{
"query":map[string]interface{}{
"term":map[string]string{"user:"kimchy"},
},
}
core.SearchRequest(true, "github", "Issues", qry, "", 0)
A Direct Search using the query string Api :
core.SearchUri("github", "Issues", "user:kimchy", "", 0)
A Filtered search Search DSL :
out, err := Search("github").Filter(
Filter().Exists("repository.name"),
).Result()
example:
import "github.com/mattbaird/elastigo/api"
import "github.com/mattbaird/elastigo/core"
// Set the Elasticsearch Host to Connect to
api.Domain = "localhost"
// api.Port = "9300"
indexer := core.NewBulkIndexerErrors(10, 60)
done := make(chan bool)
indexer.Run(done)
go func() {
for errBuf := range indexer.ErrorChannel {
// just blissfully print errors forever
fmt.Println(errBuf.Err)
}
}()
for i := 0; i < 20; i++ {
indexer.Index("twitter", "user", strconv.Itoa(i), "", nil, `{"name":"bob"}`)
}
done <- true
