Welcome to For the Sake of Search! An unaffiliated podcast that talks about all things search engineering. We'll be covering: search infrastructure, when should I use X search vendor, how to do search relevancy, describing search to your grandmother.
And many many more things. If you would like to be a guest on the show please reach out! I am @dtaivpp on Relevancy Slack (https://opensourceconnections.com/community/) and @taidesu on Bluesky (https://bsky.app/profile/taidesu.bsky.social).
Search is changing fast. AI has raised user expectations, vector search has brought in a wave of new builders, and more teams are realizing that similarity alone does not mean relevance. In this episode, we’re joined by Dom Couldwell, Product Manager for OpenSearch at IBM, to talk about intent-aware search. What does “intent” mean, how teams can uncover it, and why search needs to be treated as a product, not just infrastructure. We’ll explore query intent, product intent, journey intent, expensive vs. efficient search strategies, and the growing identity crisis search faces in the age of AI. This episode is brought to you by https://relevan.dev (https://relevan.dev).

Understanding users at internet scale with Tito Sierra
How can we determine what users are looking for when they search? We’re joined by Tito Sierra, Director of Product Management at Yahoo, to break down how modern search engines interpret queries at scale. Most companies get this wrong and we'll discuss why. Lets dive into query understanding, intent classification, and the real product and engineering work behind making search feel “smart.” If you’ve ever wondered why search fails, or how to fix it, this episode lays the foundation. This episode is brought to you by relevan.dev (http://relevan.dev) - search that sells.

Why shouldn't you fine tune?
So much recently I've seen companies obsessing over fine tuning. Should you fine tune your language models? Nicolay from AISBACH Data Solutions joins me this week as we talk through the many challenges that come when you fine tune language models. He's spent the last several years working with customers to get the most out of their LLM's and has some insights to share.

Hiring for Search
You wouldn't hire a network engineer to build your front end would you? Then why hire just any software engineer for search?! In this episode we talk with Brian Pedersen founder of TheSearchBar.ai (http://TheSearchBar.ai) to talk a bit more about the challenges of hiring search engineers.
There tends to be a big disconnect between companies that want to hire search engineers and engineers that are looking for companies that value their skills. Thankfully Brian is here to help give some advice so that everyone can get what they are looking for!

Good search in Postgres?!
We talk with Philippe (https://x.com/philippemnoel) from ParadeDB (https://github.com/paradedb/paradedb) about search on Postgres. Historically search on Postgres has been really bad but it doesn't have to be anymore. Let's go into a bit of the why search on Postgres is the way it is. This will help us understand why it got to where it is and how ParadeDB is making it better.
Session Notes:
