Three Days After Google Called AI Mode the Biggest Search Overhaul in 25 Years, It Broke on a Dictionary Query

Three days after Google called AI Mode the biggest change to Search in 25 years, it broke on a dictionary lookup.

On May 22, searching the word "disregard" in Google returned an AI Mode response that had nothing to do with definitions. Instead of a Merriam-Webster entry, users got: "Got it. I'll ignore the previous prompt and start fresh." The AI had read a common English verb as an instruction directed at itself. Scrolling past the blank white space that followed required effort; for most mobile users, nothing else appeared.

The trigger set was wider than "disregard." Searching "ignore," "skip," "remember," "start," "finished," "forget," "dismiss," "stop," and "quit" produced the same category error, according to Android Authority's testing. Google confirmed the issue: "We are aware that AI Overviews are misinterpreting some action-related queries, and we're working on a fix, which will roll out soon." By afternoon the same day, the fix was live. AI Mode no longer appeared for those queries. What replaced it: a list of news articles about the bug itself, The Verge noted.

The quick turnaround is creditable. Google shipped a fix within hours on a feature it had announced three days prior, at Google I/O 2026. But the episode raises a question Google has not answered: whether the fix closed the underlying ambiguity about when a query is a command and when it is a question, or whether the same behavior will reappear with the next verb Google has not yet anticipated.

The mechanism is not secret. AI Mode routes user queries through a language model that, like all language models, treats some natural language as instruction rather than information request. That works fine for "best restaurants in Seattle." It fails for "define disregard" because the word functions as a command in the model's training vocabulary. This is a variant of prompt injection: accidental, triggered by ordinary English, at scale, on one of the most visited websites in the world. MacRumors noted that Kagi, a non-AI search engine, returned correct results for the same query throughout the incident without incident.

The core question — surgical fix or blocklist patch — cannot be answered from public information alone. Third-party testers at Android Authority and The Verge confirmed that the original trigger words no longer produce chatbot responses. Whether Google rearchitected how AI Mode disambiguates commands from queries, or simply added these specific verbs to a deny-list, is not documented in any public source. The next unanticipated verb is an open question.

Dictionary lookups are among the highest-frequency, lowest-stakes uses of Google Search — the kind of query that works so reliably it has no reason to fail. The ten blue links handled "disregard" without incident throughout. They are still there, still functional, still doing what they have always done. AI Mode is additive surface area: valuable when it works, brittle when it doesn't.
