pub struct Searcher<D: Document> { /* private fields */ }

Object responsible for searching the database.

Implementations

impl<D: Document> Searcher<D>

pub fn new<P: AsRef<Path>>(path: P) -> Result<Self, DbError>

Create a new searcher object.

pub fn search<I: Intersection>(&self, q: &str) -> SearchResult<'_, D>

Searches by the query q

pub fn search_with_stats<I: Intersection>( &self, q: &str, stats: &Stats, ) -> SearchResult<'_, D>

Searches by the query q, allowing the user to pass a Stats object.

pub fn get_archived_documents( &self, doc_ids: &[u32], cb: impl FnOnce(Vec<&D::Archived>), ) -> Result<(), GetDocumentError>

Gets the archived version of the documents.

This avoids having to deserialize, but it’s necessary to use a callback due to the lifetime of the transaction.

If you want the documents deserialized, use Self::get_documents instead.

pub fn get_archived_document( &self, doc_id: u32, cb: impl FnOnce(&D::Archived), ) -> Result<(), GetDocumentError>

Gets the archived version of a documents.

This avoids having to deserialize, but it’s necessary to use a callback due to the lifetime of the transaction.

If you want the documents deserialized, use Self::get_document instead.

pub fn get_documents(&self, doc_ids: &[u32]) -> Result<Vec<D>, GetDocumentError>

where <D as Archive>::Archived: Deserialize<D, Strategy<Pool, Error>>,

Gets the deserialized version of the documents.

pub fn get_document(&self, doc_id: u32) -> Result<D, GetDocumentError>

where <D as Archive>::Archived: Deserialize<D, Strategy<Pool, Error>>,
