Overview ¶
Package weaviate 提供 Weaviate 向量数据库集成
Weaviate 是一个开源的向量搜索引擎，支持语义搜索和混合搜索。
特性：
- 内置向量化模块 (text2vec-openai, text2vec-cohere 等)
- 支持 BM25 关键词搜索
- 支持混合搜索 (向量 + 关键词)
- GraphQL API
- 多租户支持
使用示例:
store, err := weaviate.NewStore(ctx,
weaviate.WithHost("localhost:8080"),
weaviate.WithScheme("http"),
weaviate.WithClass("Document"),
)
defer store.Close()
