On Drupal Answers, I am trying to look for drupal_render, which is the name of a Drupal function. If I search for drupal_render, I get posts containing Drupal, render, or drupal. If I search for code:"drupal_render", I get only posts where drupal_render is contained in a code block.
Is there a way to tell the search page to look only for drupal_render?
I tried with "drupal_render", and
"drupal\_render" (escaping the underscore), but the result doesn't change much from when I search for drupal_render.
