Short and sweet:
Semantic search; a search approach that interprets the meaning and intent behind a query rather than matching only the literal keywords typed in, allowing more conversational or vaguely worded searches to still return relevant results.
The underlying capability that makes modern search engines and AI answer engines able to understand natural, conversational questions.

Older search engines relied heavily on matching the exact words in a query to the exact words on a page, which meant a search for best budget laptop for college might miss a genuinely relevant page that used different phrasing, like affordable student computer. Semantic search closes that gap by analyzing the relationships between words and concepts, understanding that budget and affordable are related, and that laptop and computer likely refer to the same thing in this context. This shift is a big part of why keyword-stuffing lost effectiveness as an SEO tactic, and why writing naturally around a topic, covering related concepts and synonyms, now tends to perform better than repeating one exact phrase.
A shopper searching cheap sneakers for running might still see results for affordable running shoes, since semantic search recognizes the terms are closely related.
A content writer covering electric vehicle range anxiety could naturally include related terms like charging infrastructure and battery degradation, which semantic search uses to confirm topical relevance.
A voice assistant answering a conversationally phrased question relies on semantic search to interpret intent, since spoken queries rarely match a page’s exact wording.
