pub fn query_tag(&self, tag: &str) -> Vec<MemoryId>

Get all memory ids that have the given tag.

pub fn query_tags_and(&self, tags: &[&str]) -> Vec<MemoryId>

Get memory ids that have ALL given tags (intersection).

pub fn query_tags_or(&self, tags: &[&str]) -> Vec<MemoryId>

Get memory ids that have ANY of the given tags (union).

pub fn remove_all(&self, id: MemoryId)
