A developer seeking advice on building a retrieval-augmented generation (RAG) system for government and internal organizational documents asks about optimal chunk sizes for BM25 and semantic search (c…
A pattern in RAG implementations shows that retrieval, not the language model, is the root cause of incorrect answers, according to a technical analysis. The article argues that semantic search using …
A new benchmark, ORCA-bench, shows that frontier language model agents achieve only 25.3% root cause analysis accuracy on Medium-difficulty oncall tasks and 10.0% on Hard tasks, with the best performa…
A developer who built CourtGPT.ai to serve 6.7M+ legal records shares 18 months of lessons on production RAG systems. Key findings include that hybrid search (BM25 + vector) achieves 92% recall at top…
PGSync Pro adds real-time semantic and hybrid search to PostgreSQL, re-embedding vectors only when meaning changes and keeping data within the user's infrastructure. The tool, built on the open-source…
Amazon Kendra is a managed enterprise search service that uses a proprietary ML model to index documents and return relevant snippets or generated answers. The service connects to data sources like S3…
Oracle's Siebel 26.6 introduces RAG-powered search using an OpenSearch vector pipeline to solve the problem of support reps re-solving the same ticket due to keyword search limitations, according to a…
OpenSearch 3.7, released in July 2026, delivers a 5.5x faster vector search at k=1000 and native Prometheus querying in OpenSearch Dashboards without requiring reindexing or data migration. The update…
OpenSearch is a common choice for vector search in production RAG systems, but tuning vector retrieval involves trade-offs between recall and latency. The article explains how Approximate Nearest Neig…
AWS engineers demonstrated troubleshooting agentic AI using OpenTelemetry and OpenSearch to gain insights into system performance and data before and during production.…
Attribute Knowledge RAG (AK-RAG) prevents large language models from inventing nonexistent fields by indexing governed attribute catalogs instead of documents, forcing field selection through retrieva…
Retrieval-augmented generation (RAG) pipelines are failing in production because most teams focus on the retrieval and generation layers while neglecting data quality, according to experts. Mayank Bho…
One Desk AI is a system that answers employee questions by automatically routing queries to internal documents, databases, or the web using four specialized agents. It uses semantic search, verified S…
SSH tunnels enable secure access to internal network services through port forwarding. Local port forwarding allows a local machine to access a remote service via an SSH connection, while remote port …
A developer detailed three vulnerabilities in the AI-coding-agent stack, including a supply chain worm that persists in developer toolchain configs, an abuse of shell built-ins to bypass Cursor's comm…
Amazon Web Services announced the general availability of the next generation of Amazon OpenSearch Serverless, featuring a redesigned architecture that delivers 20 times faster resource provisioning, …
At TopVideoHub, a video aggregator pulling trending content from nine Asia-Pacific regions every four hours, engineers migrated from SQLite FTS5 to OpenSearch to implement typo-tolerant search across …
A lone attacker published 14 malicious npm packages that mimicked popular OpenSearch and Elasticsearch libraries. Microsoft identified and removed the packages, which were designed to trick developers…
AWS has redesigned OpenSearch's architecture to better support agent workloads, moving away from its original search-focused design. The change aims to optimize the platform for AI-driven applications…
