Talk #1 by Amir Hossein Rassafi | Head of Platform at Condukt
Title: From PostgreSQL to Elasticsearch: Migrating a Fuzzy Name Search at Scale
What happens when your search quality is good but your database can't keep up? In this talk, we'll walk through a real migration from PostgreSQL's pg_trgm to Elasticsearch — driven by growing latency and database pressure.
We'll cover how to preserve trigram-like behaviour using n-grams, prefixes, keywords, and shingles, how to validate the new system with real queries and synthetic typo cases, and the production details that made the migration safe: replication, checkpointing, lag handling, and replayable indexing.
A practical talk for anyone dealing with fuzzy search at scale — or planning a migration where quality, performance, and reliability all matter.

Talk #2 by Akbar Gumbira, Senior Machine Learning Engineer and Antonio Morais, Machine Learning Engineer | Elastic
Title: Power of Three - turning scanned documents into ranked answers with Jina OCR, Omni and Reranker on EIS
Take a folder of scanned documents and convert it into a searchable index with the help of three Jina models: OCR extracts the text, Omni v5 embeds the image and text into a shared vector space, and Reranker v3.5 surfaces the right page at the top. We will detail the inner workings of each model, and then show how you can build an end-to-end pipeline with Jina on Elastic Inference Service
