How to use search_type from elasticsearch javascript library

Question

I am trying to execute a search query with search_type of count with the elasticsearch.angular.js build from the npm module.

I can execute the query like this:

POST /index1/type1/_search?search_type=count

 {
   "aggs": {
   "reviews": {
     "nested": {
       "path": "reviews"
      }
    }
  }
}

but when I try to translate the query to the .js api, I get an error. My code looks like this:

  var requestObject = {
      index:'index1',
      type:'type1',
      searchType: 'count',
      body: {
        query:{
          aggs: {
            reviews: {
              nested: {
                path: "reviews"
              }
            }
          }
        }
    };
    esClient.search(requestObject)

The trace looks like this:

  console.js:1 DEBUG: 2015-08-04T15:28:59Z
      starting request { method: 'POST',
        path: '/index1/type1/_search',
        body: { aggs: { reviews: [Object] } },
        query: { search_type: 'count' } }

That looks OK to an elasticsearch newbie, but the request completes with an error: ReferenceError: count is not defined.

What am I missing here please?

It's probably not related (never know though), but the aggs part needs to be a direct child of the body element, i.e. not nested inside the query element. Can you make that change and try again to see if that makes any difference? — Val

I'm pretty sure that that's a JS error and not an ES error. Can you post how you're handing the response of esClient.search()? — robertklep

@robertkliep I'm not at my computer now, but I am handling the response with the promise syntax. — kpg

@robertklep: just checked my response-handling code and sure enough I was console.logging something called 'count'. I'll blame it on the end of a long day, but thanks for your help! — kpg

It turned out that my problem was a stupid error on my part (thanks @robertklep for pointing it out). The code above actually works correctly. As I was not able to find an example of using using searchType from the api, I am leaving this here in the hope it will be useful to somebody else.
