title: Elasticsearch indices eating too much space
body: <p>I'm using Elasticsearch 7.5.2 on Ubuntu. Recently, I began using Elasticsearch to display relevant search results on every page load. This shot up the volume, but I also found out that it has created large index files. Note that I'm using 'app-search' to power my queries. </p>
  
  <p>Here's the sample index files that are occupying too much space:</p>
  
  <pre><code>.app-search-analytics-logs-loco_togo_production-7.1.0-2020.01.26 =&gt; 52 GB
  .app-search-analytics-logs-loco_togo_production-7.1.0-2020.01.27 =&gt; 53 GB
  </code></pre>
  
  <p>I tried deleting these using CURL, but they reappear and show lesser space (~5 GB each). </p>
  
  <p>I want to know if there is a way to control these indexes. I'm not sure what purpose do these indices solve and if there is a way to prevent them?</p>
