title: How to search for JIRA issues NOT in filter
body: <p>How can I find issues which are not a member of an existing filter?</p>
  
  <p>I have an agile board which naturally have a filter. Some issues within our project has been filtered from showing on this agile board and now I want a JQL search that can find all these issues, not visible within our agile board.</p>
  
  <p>We have JIRA version 6.4.5.</p>
  
  <p>Just to show what I have tried:</p>
  
  <pre><code>project = MyProj AND issueFunction in expression("", "filter != 1234")
  </code></pre>
  
  <p>.. and:</p>
  
  <pre><code>project = MyProj AND filter != 1234
  </code></pre>
  
  <p>.. which gives this error:</p>
  
  <pre><code>Field 'filter' with value '1234' matches filter 'MyProj' and causes a cyclical
  reference, this query can not be executed and should be edited.
  </code></pre>
  
  <p>The content/JQL of filter <code>1234</code> is:</p>
  
  <pre><code>project = MyProj AND (component != "Special Work" OR component is EMPTY) ORDER BY Rank ASC
  </code></pre>
  
  <p>I do not have access to the REST API, if this is required.</p>
