Overview

Package boltdb implements a store.KVStore on top of BoltDB. It supports the following options:

"bucket" (string): the name of BoltDB bucket to use, defaults to "bleve".

"nosync" (bool): if true, set boltdb.DB.NoSync to true. It speeds up index operations in exchange of losing integrity guarantees if indexation aborts without closing the index. Use it when rebuilding indexes from zero.

type Reader

type Reader struct {
	// contains filtered or unexported fields
}

}

func (*Store) Close

func (bs *Store) Close() error

func (*Store) Compact

func (bs *Store) Compact() error

Compact calls CompactWithBatchSize with a default batch size of 100. This is a workaround for github issue #374.

func (*Store) CompactWithBatchSize

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

CompactWithBatchSize removes DictionaryTerm entries with a count of zero (in batchSize batches) Removing entries is a workaround for github issue #374.
