status updates

• 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.

Search Examples

A Faceted, ranged Search using the Search DSL :

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, "")

A Direct Search using the query string Api :

core.SearchUri("github", "Issues", "user:kimchy", "")

A Filtered search Search DSL :

out, err := Search("github").Filter(
  Filter().Exists("repository.name"),
).Result()

Adding content to Elasticsearch

examples:

// add single go struct entity
response, _ := core.Index(true, "twitter", "tweet", "1", NewTweet("kimchy", "Search is cool"))

// you have bytes
bytesLine, err := json.Marshall(tw)
response, _ := core.Index(true, "twitter", "tweet", "2", bytesLine)

// Bulk Indexing 
core.IndexBulk("twitter", "tweet", "3", &time.Now(), NewTweet("kimchy", "Search is now cooler"))
