SQLite 搜索引擎存储

管理一个 SQLite 数据库文件,包含:

  • entities FTS5 虚拟表(全文搜索)

Implementations§

Source§

impl SearchStore

Source

pub fn open(path: impl AsRef<Path>) -> Result<(Self, bool)>

打开或创建数据库,初始化表结构。

设置 WAL 模式和 busy_timeout 以支持并发读取。 返回 (store, need_reindex):need_reindex=true 表示旧 schema 已 迁移重建(表为空),调用方必须全量重索引文本(增量路径不能只 补 changed_files,否则旧实体索引丢失)。

Source

pub fn insert_entities_batch(&self, items: &[(CodeNode, String)]) -> Result<()>

批量插入实体到 FTS5 表

Source

pub fn search_fts( &self, query: &str, limit: usize, ) -> Result<Vec<(CodeNode, f64)>>

FTS5 全文搜索,按 BM25 相关性排序

Source

pub fn delete_entities_by_file(&self, file_path: &str) -> Result<usize>

删除指定文件的所有 FTS5 条目

参数与 file_path 列同基准:写入时已归一化(票 08),删除键也归一化, 保证 Windows 反斜杠路径(调用方传入)与入库正斜杠键精确匹配。

Source

pub fn entity_count(&self) -> Result<usize>

获取 FTS5 表中的文档总数

Source

pub fn clear_entities(&self) -> Result<()>

清空 FTS5 表
