It absolutely is, but there&#x27;s even more to it than that. From their documentation (<a href="http:&#x2F;&#x2F;www.tiobe.com&#x2F;index.php&#x2F;content&#x2F;paperinfo&#x2F;tpci&#x2F;programminglanguages_definition.html" rel="nofollow">http:&#x2F;&#x2F;www.tiobe.com&#x2F;index.php&#x2F;content&#x2F;paperinfo&#x2F;tpci&#x2F;progra...</a>):<p>&quot;In order to filter out false positives, two mechanisms are used. First of all a confidence is defined for a language. By default the confidence is 100%, but for some difficult search queries such as &quot;Basic Programming&quot;, the confidence will be lower. Apart from the confidence, sometimes also exceptions or mandatory additions are used to weed out false positives.&quot;<p>What they do is that add the term &quot;+Google&quot; to the search terms, yet for the other incredibly popular word &quot;Rust&quot;, they don&#x27;t add &quot;+Mozilla&quot;. TIOBE is laughable.
