title: Django Model - Dynamic case-insensitive match query
body: <p>Very simple.
  I need a IN with CaseInsensitive and Full Like.</p>
  
  <p><strong>Example</strong></p>
  
  <p>Search Probe: "Crit,Norm"</p>
  
  <p>I need to find all of this rows with column's value: "critical, Crit, crit, normal, Normal"</p>
  
  <p><strong>PostgreSql</strong></p>
  
  <p>Searching on google, I found Postgres function "similar to"</p>
  
  <p><code>lower(column_name) similar to '%(crit|norm)%';</code></p>
  
  <p>Is there a way to make it in Django?</p>
  
  <p><strong>Adding New Info after Yugandhar Chaudhari response</strong></p>
  
  <p>The question was not complete. The search probes are inside an array.
  I would like something like this:</p>
  
  <p><code>probes = ["Crit","Norm"]
  model_name.objects.filter(columnname_icontains_in = probes)</code></p>
