AI search engines don't run your keyword. They fan it out into 10-50 sub-queries behind the scenes (Google AI Mode calls this "query fan-out"; ChatGPT Search and Perplexity do it differently but the mechanic is the same) then blend the retrieved answers. Type one seed keyword. See the pack the engine is probably running.
A noun phrase works best — product, topic, problem, or question. Optional modifiers shape which intent buckets appear.
