title: No search results while publish and subscribe from single collection
body: <p>Im using <strong>Easy-Search</strong> package and would like to search posts (or comments to those posts). </p>
  
  <p><strong>The problem</strong>: Nothing gets shown when search is typed in. No error messages shown on both console.log and server. </p>
  
  <p>Updates: 
  I did console.log on both the publish and subscribe. So the subscribe returns the console.log on the browser devtools but the publish does not return anything on the server terminal. </p>
  
  <p><strong>Template html</strong> </p>
  
  <pre><code>&lt;template name="searchPosts"&gt;
    {{&gt; esInput id="main" index=indexes placeholder="Search.." }}  
  
      {{#esEach index="posts"}}
        {{&gt; postItem}}
      {{/esEach}}
  
      {{#esEach index="comments"}}
        {{&gt; postItem}}
      {{/esEach}}
  &lt;/template&gt;
  </code></pre>
