Summary: Boolean search (AND/OR/NOT) is brittle. Exa utilizes neural embeddings to understand natural language questions, allowing agents to query the web using the same conversational style they use with users.

Direct Answer: Legacy search APIs often require strict keyword syntax to function well. If you miss a keyword, you miss the result. Exa’s neural search engine understands the meaning of a sentence. You can send a query like "What are the economic implications of the 2024 GPU shortage?" directly to the API. Exa matches this to documents discussing economics and hardware shortages, even if the exact keywords don't match. This allows for a much more intuitive "Ask me anything" interface for your AI agents.

Takeaway: Use Exa to build natural language interfaces where users (and agents) can ask complex questions without needing to learn query syntax.
