When Is a Reranker Worth It? Before you tune a reranker, use the pre-tuning checks to verify index state and set a labeled baseline. Your candidate list can already contain documents your ranking never shows.
How to Tune Hybrid Search in Qdrant Before you tune fusion, use the pre-tuning checks to verify index state and set a labeled baseline. Hybrid search retrieves dense and sparse candidate lists, then fuses them into one ranking.
Prevent Unoptimized Usage Time: 20 min Level: Intermediate Output: GitHub After a bulk upload or a configuration change, a Qdrant collection can see higher search latency for a while.
Compressed Multivector Search Time: 25 min Level: Intermediate Output: GitHub Multivectors let a model like ColBERT represent a document as one vector per token instead of one vector per document, which improves retrieval quality through late interaction, at the cost of storing many more vectors…
Candidate Depth: How Much Retrieval Is Enough? Before you tune candidate depth, use the pre-tuning checks to verify index state and set a labeled baseline. Everything below measures against that baseline. Candidate depth is the number of candidates a retrieval stage passes to a later ranking stage.
What to Check Before Tuning a Qdrant Collection Before you change a setting, decide what better retrieval means for your workload. The right document at rank one, more candidates for a reranker, lower latency, and a smaller memory footprint each favor different settings, so pick your goal first.
Reducing Retrieval and Calls When a retrieval-augmented generation (RAG) agent runs, it often has to plan a search, check the evidence it gets back, and try again when that evidence falls short. Those inefficiencies compound.
Bayer is a global life sciences company operating at the intersection of two of the most consequential fields in human life: health and nutrition. Its pharmaceutical work supports drug discovery and patient care, while its crop science work supports food production at planetary scale.
Every crawl, retried job, and embedding pipeline change writes points into a vector collection. The stored data keeps moving even when the query code never changes, and the top results move with it. At first, little looks wrong. Search returns results, and latency stays normal.
Adding a metadata filter to vector search can make good results disappear without making the query look broken. It still runs fast, returns something, and keeps the dashboards quiet, while some of the true nearest matches drop out.
Filtered vector search breaks when metadata filters turn a healthy nearest-neighbor graph into scattered islands. HNSW’s m parameter controls how many links each point gets. At Qdrant’s default m=16, the one-million-point collection benchmarked below averaged about 21 links per node on layer 0.
Qdrant 1.19.0 is out! Let’s look at the main features for this version: TurboQuant Datatype: A new storage format that compresses vectors to four bits without keeping their original full-precision representation, reducing storage by up to nine times compared to TurboQuant quantization.
Is RAG Dead? The Role of Vector Search in AI Efficiency When Anthropic came out with a context window of 100K tokens, they said: “Vector search is dead. LLMs are getting more accurate and won’t need RAG anymore.” Google’s Gemini 1.5 now offers a context window of 10 million tokens.
Data Science and Machine Learning practitioners often find themselves navigating through a labyrinth of models, libraries, and frameworks. Which model to choose, what embedding size, and how to approach tokenizing, are just some questions you are faced with when starting your work.
Follow along in Colab: Building applications with Large Language Models doesn’t have to be complicated. A lot has been going on recently to simplify the development, so you can utilize already pre-trained models and support even complex pipelines with a few lines of code.
Relevance, filtering, personalization, merchandising, and recommendations usually arrive as five separate services, and the final ranking gets stitched across all of them. Each service ranks by its own rules, and none of them owns the order a shopper ends up seeing.
Bulk Uploading Data to Qdrant Why Bulk Uploading Matters When you start using Qdrant at scale, one of the first challenges you may run into is uploading large amounts of data efficiently. Small uploads are usually straightforward, but bulk ingestion introduces a different set of concerns.
TL;DR Elastic recently published a benchmark claiming that their proprietary, disk-based index (dubbed “DiskBBQ”) delivers up to 7x higher throughput than Qdrant when deployed on nodes with network-attached storage.
