title: How to define parameters with square brackets in OpenAPI (Swagger)?
body: <p>I have an endpoint with query parameters that use square brackets:</p>
  
  <pre><code>GET /info?sort[name]=1&amp;sort[age]=-1
  </code></pre>
  
  <p>Here, <code>name</code> and <code>age</code> are the field names from my model definition.</p>
  
  <p>How can I write an OpenAPI (Swagger) definition for these parameters?</p>
