**Zvec** is an open-source, in-process vector database — lightweight, lightning-fast, and designed to embed directly into applications. Battle-tested within Alibaba Group, it delivers production-grade, low-latency and scalable similarity search with minimal setup.

> [!Important]
> 🚀 **v0.5.0 (June 12, 2026)**
> 🚀 **v0.6.0 (July 20, 2026)**
>
> - **Full-Text Search (FTS)**: Native full-text search — attach an FTS index to any string field and query it with natural-language or structured expressions, no external search engine required.
> - **Hybrid Retrieval**: Combine full-text, dense-vector, and sparse-vector retrieval in a single query call, with scalar filtering and reranking.
> - **DiskANN Index**: New on-disk index that keeps the bulk of the index on disk, drastically cutting memory usage for large-scale datasets.
> - **Ecosystem & Platforms**: New official [Go](https://github.com/zvec-ai/zvec-go) / [Rust](https://github.com/zvec-ai/zvec-rust) SDKs, the [Zvec Studio](https://github.com/zvec-ai/zvec-studio) visual tool, and RISC-V support.
> - **Group-By Search**: Retrieve top-K results per group instead of globally (group-by deduplication) across Flat, HNSW, HNSW-RaBitQ, and sparse indexes.
> - **Random Rotation Quantization**: Optional random rotation for INT8/INT4 quantization distributes variance evenly across dimensions, significantly boosting recall.
> - **Enhanced Full-Text Search**: Upgraded FTS pipeline with a Unicode UAX #29 standard tokenizer, UTF-8 / ASCII folding, and a Snowball-based stemmer supporting 34+ languages.
> - **Faster & More Robust**: Block-max skip speeds up FTS conjunction queries by 22–38%, plus a new DiskANN C API and numerous stability fixes.

> - **全文检索（FTS）**：原生全文检索能力——可为任意字符串字段挂载 FTS 索引，使用自然语言或结构化表达式检索，无需外接搜索引擎。
> - **混合检索**：在单次查询调用中融合全文、稠密向量和稀疏向量检索，并支持标量过滤与重排。
> - **DiskANN 索引**：全新磁盘索引，将索引主体存于磁盘，大幅降低大规模数据集的内存占用。
> - **生态与平台**：全新官方 [Go](https://github.com/zvec-ai/zvec-go) / [Rust](https://github.com/zvec-ai/zvec-rust) SDK、可视化工具 [Zvec Studio](https://github.com/zvec-ai/zvec-studio)，以及 RISC-V 架构支持。
> - **分组检索（Group-By）**：支持按分组去重检索，返回每个分组的 Top-K 结果而非全局 Top-K，覆盖 Flat、HNSW、HNSW-RaBitQ 与稀疏索引。
> - **随机旋转量化**：为 INT8/INT4 量化新增可选的随机旋转能力，将方差均匀分布到各维度，显著提升召回率。
> - **全文检索增强**：升级 FTS 文本分析管线，新增基于 Unicode UAX #29 的标准分词器、UTF-8 / ASCII 折叠，以及基于 Snowball、支持 34+ 种语言的词干提取过滤器。
> - **更快更稳健**：Block-max 跳跃优化使 FTS 合取查询提速 22–38%，同时新增 DiskANN C API，以及大量稳定性修复。
