How to get the total count of search result in Coveo result template

Question

According to this thread, the "index" is the built-in variable that can be used in the Coveo search result templates. Is there a document that list all available built-in" variables in the scope of result template? especially I needed is to use the total count of the search result to have a logic, inject the survey block after 3rd search result, or append to last if the total count is less than 3.

<script class="result-template" type="text/underscore">
    <div>
        {{ if (index == 3 || index == totalCount ) { }}
            <div class="coveo-result-row survey-block">
                 Are these results helpful?
                 <a href="#" class="survey-yes">Yes</a>
                 <a href="#" class="survey-no">No</a>
            </div>
        {{ } }}
    <div>

The coveo for Sitecore shows the total number of count with the result like this.

However you can try this code to get it and show it where you want with your page.

Coveo.$(function() {
 var options = <%= Model.GetJavaScriptInitializationOptions() %>;

 // ADDED CODE -->
 Coveo.$('#search')
 .on('buildingQuery', function (e, args) {
 args.queryBuilder.expression.add('search');
 })
 .on('querySuccess', function (e, args) {
 console.log('Query returned ' + args.results.totalCount + ' results
in ' + args.results.duration + 'ms.');
 });
 // <-- ADDED CODE
 Coveo.$('#search').coveoForSitecore('init', options);
});

Using the args.results you can also get the attributes of the result returned.

Hope this helps.
