title: SPARQL query to retrieve data with different datatype (string)
body: <p>I am writing a SPARQL query to retrieve answers for the competency question. I want to retrieve all persons who have level of distress &quot;not too disturbing&quot;.</p>
  <pre><code>select *
  where
  {
    ?person ocd:hasInsight  ?insight;
    ocd:hasThought ?thought;
    ocd:hasEmotion ?emotion;
    ocd:hasDistressLevel ?severitycontrol.
    FILTER (?severitycontrol = ocd:Not too disturbing) 
  }
  </code></pre>
  <p>I am new at this and could not figure out how to fix that.</p>
