How Does AI Search Work? Simple Explanation of Retrieval and Synthesis
AI search usually combines two steps: retrieving relevant information and synthesising that information into a direct answer.
Short answer
Traditional search returns links. AI search retrieves sources and uses a model to turn those sources into a response.
Retrieval vs synthesis
Retrieval is the part that finds relevant information. Synthesis is the part where the model reads, combines, and explains it.
The useful mental model
AI search is not magic search. It is search plus summarisation, which means the quality of the answer depends on both the sources and the synthesis.
Common questions
How is AI search different from Google search?
Traditional search usually gives you ranked links. AI search often gives a direct answer based on sources it has retrieved.
Can AI search still be wrong?
Yes. It can retrieve weak sources, misunderstand them, or synthesise them incorrectly.
What should I check in an AI search answer?
Check the sources, whether they support the claim, and whether the model is summarising or adding unsupported details.
