Struct IndexWriter 

pub struct IndexWriter<D: DirectoryWriter> { /* private fields */ }

Async IndexWriter for adding documents and committing segments

Internally manages parallel segment building based on num_indexing_threads config. Documents are distributed across multiple segment builders round-robin style.

Implementations

impl<D: DirectoryWriter> IndexWriter<D>

pub async fn create( directory: D, schema: Schema, config: IndexConfig, ) -> Result<Self>

Create a new index in the directory

pub async fn open(directory: D, config: IndexConfig) -> Result<Self>

Open an existing index for writing

pub fn schema(&self) -> &Schema

Get the schema

pub fn set_tokenizer<T: Tokenizer>(&mut self, field: Field, tokenizer: T)

Set tokenizer for a field

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

Add a document

Documents are distributed across internal segment builders based on num_indexing_threads config. When any builder reaches max_docs_per_segment, it is committed to disk in the background.

pub async fn commit(&self) -> Result<()>

Commit all pending segments to disk

Commits all internal segment builders in parallel.

pub async fn force_merge(&self) -> Result<()>

Force merge all segments into one
