Search has a problem: users aren't expert query-crafters.
Large Language Models (LLMs) can help bridge this gap. LLMs are what ChatGPT, Claude, Gemini, and other new (but incredibly widely used) chatbots are based on. They're the hot new thing that's put AI back in the spotlight over the last few years.
LLMs are super useful in search – they can be used before or after the actual search takes place. In this chapter, we'll focus on using LLMs before the search to help improve the query itself.
