If you search for
'console' is undefinedhere in the forum you will be directed to a search result page of
'console' is: Search results for ‘"‘console’ is undefined"’ - Discourse Meta
Not getting highlighted:
Even if the search term does appear correctly in the search field (I don’t understand when it gets lost and when it works) the “undefined” string will not be highlighted in the search results: Search results for ‘“Error: Cannot read property ‘name’ of undefined”’ - Ionic
Edit: The “not getting highlighted” thing appears to be a bug when you manually search for it again after opening the URL, then the search term appears correctly in the search box, but really is still broken. 2) might be solved when 1) is solved then.
