How to extract result from org.elasticsearch.search.suggest.Suggest object on scala


I got the working solution from this link - https://groups.google.com/forum/#!topic/elasticsearch/FwRv0D5qIi8

The solution is -

    import
org.elasticsearch.node.NodeBuilder._
    import
org.elasticsearch.search.suggest.completion.CompletionSuggestionBuilder
    import
org.elasticsearch.search.suggest.completion.CompletionSuggestion

    // Build query for searching the client.
    var suggester = new
CompletionSuggestionBuilder("first_name")
    suggester.text(query)
    suggester.field("suggest")
    suggester.size(5)
    var suggestions =
client.prepareSuggest("autocomplete")
                      .addSuggestion(suggester)
                      .execute()
                      .actionGet()

    val suggest = suggestions.getSuggest()

    if (suggest.size > 0) {
      val optIter = suggest
                  .iterator()
                  .next()
                  .getEntries()
                  .get(0)
                  .iterator()

      while(optIter.hasNext()){
          println(optIter.next().getText())
      }
    }

I know this question was little specific to particular API usage. I'm not accepting my answer my self now :)

I am not getting placeholder in kendo dropdownlist.Can any one suggest me for solution
There is no "placeholder" property of kendo drop-down widget. Instead you can do that by placing an "optionLabel" property.i.e. var data1 = [ //this part is related to the above html tag {text: "org1", value: "1", color: "#a8a9aa", selected:true }, {text: "org2", value: "2", color: "#000", selected: false }, {text: "org3", value: "3", color: "#0

Ways to improve Auto Suggest from client Side
To make the response fast, I suggest cache the indexes in-memory. Indexing 1,20,000 categories may not be huge. Also you can try Redis's autocomplete. This would easy to implement and would have very fast response time.
