Modifier and Type	Method	Description
void	begin()	Begins a transaction.
void	clear()	Clears the indexes.
void	clearContexts(Resource... contexts)	This should be called from within a begin-commit-rollback block.
void	commit()	Commits any changes done to the LuceneIndex since the last commit.The semantics is synchronous to SailConnection.commit(), i.e. the LuceneIndex should be committed/rolled back whenever the LuceneSailConnection is committed/rolled back.
