Lightning-Fast Retrieval with Robust Support

  • November 05, 2025
  • Review provided by G2

What do you like best about the product?
I truly love using Zilliz for building our video retrieval tool as it has greatly enhanced our ability to convert each frame of a video into vectors and store them effectively in Zilliz Cloud. This functionality allows for accurate and efficient searches for corresponding images or videos, whether making searches from text to images or vice versa. The support from Zilliz is impeccable, with a very active community and extremely reliable database systems, which gives us a great deal of confidence. The most impressive aspect is the retrieval speed; it is exceptionally fast, allowing us to search through millions of vectors in just 200 milliseconds, which is critical for our operations. Additionally, the ability of Zilliz to handle a large capacity of data further boosts its value, making our data management and retrieval processes smooth and efficient.
What do you dislike about the product?
I think the number of vector columns supported in a single collection is a bit low, it seems to be 4 or 8. We would like to be able to search across more dimensions.
What problems is the product solving and how is that benefiting you?
I use Zilliz to convert video frames into vectors stored in Zilliz Cloud, facilitating accurate image or video retrieval. The retrieval speed is extremely fast, processing millions of vectors in 200 milliseconds, and the capacity is very large.

Convenient Hybrid Retrieval with Room for Documentation Improvement

  • November 05, 2025
  • Review provided by G2

What do you like best about the product?
I really appreciate how Zilliz supports hybrid retrieval, combining both vector and keyword searches. This feature is incredibly beneficial as it provides me with more accurate, context-aware results and ensures that I do not miss important exact matches. It’s very convenient to use, making my workflow more efficient. Additionally, the initial setup was a breeze thanks to Docker Compose and the clear documentation which guided me quickly through getting started.
What do you dislike about the product?
I find that sometimes the documentation could be more detailed, especially for advanced configurations and performance tuning. They could include more real-world configuration examples, detailed parameter explanations, and best practices for optimizing performance with large-scale hybrid retrieval workloads.
What problems is the product solving and how is that benefiting you?
I use Zilliz for RAG, enhancing search accuracy and document storage with similarity search and hybrid retrieval, combining vector and keyword search for context-aware results.

Efficient Zilliz for Entity Alignment, Disambiguation, and RAG Recall in Knowledge Graphs

  • November 05, 2025
  • Review provided by G2

What do you like best about the product?
I love how Zilliz excels at scalability and high-performance vector search, making it incredibly efficient for handling massive datasets in AI-driven tasks. In my experience, its hybrid retrieval capabilities—combining vector embeddings with knowledge graph integrations—stand out, especially for complex queries involving semantic understanding. It's easy to integrate with tools like LangChain and OpenAI embeddings, and the cloud-native features in Zilliz Cloud simplify management without sacrificing speed or accuracy.
What do you dislike about the product?
For self-hosted Milvus setups, the configuration might feel a bit involved compared to fully managed options, but Zilliz Cloud largely resolves that with its user-friendly UI and elastic scaling.
What problems is the product solving and how is that benefiting you?
Zilliz is tackling challenges in entity alignment and disambiguation within my knowledge graph project by leveraging vector embeddings and graph-based retrieval to link and resolve entities across diverse datasets, reducing ambiguities (like distinguishing similar terms in different contexts) and enabling precise multi-hop reasoning. This has streamlined entity matching, cutting down on manual corrections and improving overall graph accuracy. In the recall step of my RAG pipeline, it enhances retrieval of relevant documents through hybrid searches (vector similarity plus relational structures), minimizing hallucinations in LLM outputs and providing more complete, contextually rich responses. Overall, it's saved me significant time on data processing, boosted the reliability of my AI applications, and allowed for handling larger-scale data without performance drops—ultimately making my projects more efficient and effective.

Why I Love Zilliz: Fast Queries, Flexible Indexes, and Easy Choices for My Business

  • November 05, 2025
  • Review provided by G2

What do you like best about the product?
Zilliz is the commercial version of Milvus, and it fits different business needs really well. First, it’s super fast when it comes to queries—super impressive. Then, for features, it supports both vector indexing and keyword indexing, so you’ve got way more flexible options there. And when picking the right type, it has capacity-focused, performance-focused, and tiered storage models. You can easily match what you need, whether that’s "fast response times" or "keeping costs down." Overall, it’s really practical and easy to use.
What do you dislike about the product?
Currently, it does not support slow query-related features.
Audit logs only support the Coordinated Universal Time Zero (UTC+0) time zone and cannot be adapted to other local time zones.
What problems is the product solving and how is that benefiting you?
Zilliz addresses three main challenges in unstructured data processing: it enables vector search for question topics, supports Retrieval-Augmented Generation (RAG) for large language models, and provides vector search capabilities for images.

Effortless Vector Retrieval, Seamless Setup

  • November 05, 2025
  • Review provided by G2

What do you like best about the product?
I am truly impressed by Zilliz's ability to handle a vast amount of data efficiently. Its capacity to store hundreds of millions of vector data points is remarkable. I find the vector retrieval process to be incredibly fast, characterized by its low latency, which is vital for my image similarity retrieval and content moderation needs. The platform's support for high-concurrency requests is another feature I value, as it ensures smooth operation even when handling multiple requests simultaneously. Additionally, the fact that Zilliz supports more than ten vector index types and offers rich functionality is a considerable advantage, simplifying operation and maintenance for my team. This richness in features also makes using Zilliz cost-effective. The initial setup was straightforward, simple, and clear, making it easier for us to integrate it with general-purpose embedding models. These aspects collectively make Zilliz an invaluable tool for our data storage and retrieval endeavors.
What do you dislike about the product?
There is a need for more comprehensive learning materials for Zilliz.
What problems is the product solving and how is that benefiting you?
I use Zilliz for efficient image similarity retrieval and content moderation, storing and retrieving vector data with low latency, supporting high concurrency, simplifying operations, and reducing costs.
