What Is an AI Search Engine?

A user enters a query in the search bar, and a traditional search engine compares it against the data in its index to retrieve data that matches that query. This is often referred to as keyword search, or sometimes lexical search.

A search engine that leverages artificial intelligence (AI), sometimes also referred to as an AI search engine or AI powered search, retrieves data a little differently. It still compares a query against indexed data, but it doesn’t just look for exact matches. Often, the search result it returns is further refined by semantic search to uncover the users intent or contextual similarity to layer on additional information to that query, like who’s asking or what actions they took along with entering that query. 

AI in search engines often means employing both keyword/lexical techniques along with semantic or vector search to achieve this precision in search results, resulting in hybrid search. These search techniques create a foundation for machine learning, like natural language processing (NLP), large language models, and others to offer personalized search. For example, NLP techniques allow a searcher to ask a computer a question in the same way they might ask another person — no boolean operators required.

Whether in ecommerce, customer support, or digital workplace, an AI search engine’s goal is to quickly connect a searcher with the answer they’re looking for.
