AI-Powered Search

AI-powered search refers to search systems that use large language models and other AI techniques to understand what you are actually looking for and deliver direct, synthesized answers rather than a list of links.

Beyond keyword matching

Traditional search engines match the words in your query to words in documents. If you search for "how to reduce employee turnover," a keyword search finds pages containing those exact words. AI-powered search understands the concept behind your query and can find relevant information even when different terminology is used — articles about "staff retention strategies" or "reducing attrition rates" would also surface.

How AI-powered search works

Modern AI search combines several technologies. Semantic search uses embedding models to convert both queries and documents into numerical vectors that capture meaning, then finds documents whose meaning is closest to your query. Retrieval-augmented generation (RAG) goes further by feeding retrieved documents to a language model that synthesizes a direct answer.

Types of AI search

• Conversational search: Search engines like Perplexity and Google's AI Overviews that generate written answers to your questions, citing their sources.
• Enterprise search: Tools like Glean and Elasticsearch that search across your company's internal documents, emails, and databases using semantic understanding.
• In-app search: AI-powered search within specific applications — searching your notes, codebase, or project management tool using natural language.

Benefits and trade-offs

AI-powered search saves time by giving you synthesized answers rather than requiring you to read multiple documents. It handles ambiguous or complex queries better than keyword search. However, it can sometimes generate confident-sounding answers that are wrong, blending information from multiple sources inaccurately. It is also more computationally expensive than traditional search.

The shift in information retrieval

AI search is changing how people find and consume information. Instead of learning to construct effective keyword queries, users can ask natural questions. This changes the skills needed — evaluating AI-generated answers becomes more important than knowing how to construct search queries.
