}

func (*Store) Close

func (ldbs *Store) Close() error

func (*Store) Compact added in v0.3.0

func (ldbs *Store) Compact() error

Compact compacts the underlying goleveldb store. The current implementation includes a workaround for github issue #374 (see CompactWithBatchSize).

func (*Store) CompactWithBatchSize added in v0.3.0

func (ldbs *Store) CompactWithBatchSize(batchSize int) error

CompactWithBatchSize removes DictionaryTerm entries with a count of zero (in batchSize batches), then compacts the underlying goleveldb store. Removing entries is a workaround for github issue #374.
