title: Creating a general filter for monitoring errors through log-based policies
body: <p>I am trying to create a log-based alert policy which publish on a notification channel whenever an error occurs on my project. For this, I just used a simple filter like <code>SEVERITY=ERROR</code> and created the policy.</p>
  <p>However, I have started receiving a lot of alerts whenever an user is interacting with the BigQuery UI. For example, if I write a wrong query (even if I don't run it), it will generate an error log on Cloud Logging that will be alerted by my policy.</p>
  <p>This made me considered to rewrite my filter because I don't want to monitor these kind of events. I am more interested on alerting operational errors, like a Cloud Function error, or a scheduled query's.</p>
  <p>I know I can filter by service, but I don't want to specify the services I want to monitor because I want to create a general filter rule which can be reused between projects no matter the services which are being used.</p>
  <ul>
  <li>How can I ignore these kind of errors which I shouldn't be worry about (like the ones generated on BigQuery UI) and listen only to actual errors?</li>
  <li>Can I for example stop logging this BigQuery UI errors with any setting on my project?</li>
  </ul>
