Notes from my session with @softwaredoug on query understanding. Worth a look if you're building retrieval systems.

@softwaredoug nailed this in our talk on query understanding: Agents don’t want more vector math. They want structure. They want reasoning. They want tools that work.
TOMORROW!!

Agents turn simple keyword search into compelling search experiences softwaredoug.com/blog/2025/09/2… (news.ycombinator.com/item?id=453473…)
RAG is dead. Again.
Agents will be a bigger paradigm shift than RAG for search RAG is a lot of the same old search we've always built. Agents that reason actually do quite well with simple search tools. like a dumb keyword search. softwaredoug.com/blog/2025/09/2…

Two different deep dives, same week. Wednesday's lesson's all about turning months of NLP work into simple prompts. Join @softwaredoug and me for Cheating at Query Understanding with LLMs and learn how to prompt your way to success. Link to join below:
How do you use LLMs for query understanding? Talk on Weds! Agents want structured, interpretable, predictable search tools. To use them well, you need to understand turn raw queries + conversations into structured requests maven.com/p/eebe98/cheat…
