Lucy::Index::BackgroundMerger - Consolidate index segments in the background.
my $bg_merger = Lucy::Index::BackgroundMerger->new( index => '/path/to/index', ); $bg_merger->commit;
Adding documents to an index is usually fast, but every once in a while the index must be compacted and an update takes substantially longer to complete. See FastUpdates for how to use this class to control worst-case index update performance.
my $bg_merger = Lucy::Index::BackgroundMerger->new( index => '/path/to/index', # required manager => $manager # default: created internally );
Open a new BackgroundMerger.
Optimize the index for search-time performance. This may take a while, as it can involve rewriting large amounts of data.
Commit any changes made to the index. Until this is called, none of the changes made during an indexing session are permanent.
Calls prepare_commit() implicitly if it has not already been called.
Lucy::Index::BackgroundMerger isa Clownfish::Obj.
