向量搜索引擎

Implementations§

Source§

impl VectorSearcher

Source

pub fn new(model: EmbeddingModel) -> Self

创建新的向量搜索引擎

§参数
  • model: 嵌入模型
§返回

向量搜索引擎实例

Source

pub fn add_document(&mut self, doc: Document) -> Result<()>

添加文档到索引

§参数
  • doc: 文档
§返回

成功或错误

§注意

需要 &mut self 因为 encode() 需要可变引用

Source

pub fn add_documents(&mut self, docs: Vec<Document>) -> Result<usize>

批量添加文档

§参数
  • docs: 文档列表
§返回

成功添加的文档数量

Source

pub fn search(&mut self, query: &str, top_k: usize) -> Result<Vec<SearchResult>>

语义搜索

§参数
  • query: 查询文本
  • top_k: 返回结果数量
§返回

搜索结果列表(按相似度降序)

Source

pub fn document_count(&self) -> usize

获取索引中的文档数量

Source

pub fn clear(&mut self)

清空索引
