NAME

       Lucy::Index::IndexManager - Policies governing index updating, locking, and file deletion.

SYNOPSIS

           use Sys::Hostname qw( hostname );
           my $hostname = hostname() or die "Can't get unique hostname";
           my $manager = Lucy::Index::IndexManager->new(
               host => $hostname,
           );

           # Index time:
           my $indexer = Lucy::Index::Indexer->new(
               index => '/path/to/index',
               manager => $manager,
           );

           # Search time:
           my $reader = Lucy::Index::IndexReader->open(
               index   => '/path/to/index',
               manager => $manager,
           );
           my $searcher = Lucy::Search::IndexSearcher->new( index => $reader );

DESCRIPTION

       IndexManager is an advanced-use class for controlling index locking, updating, merging,
       and deletion behaviors.

       IndexManager and Architecture are complementary classes: Architecture is used to define
       traits and behaviors which cannot change for the life of an index; IndexManager is used
       for defining rules which may change from process to process.

CONSTRUCTORS

   new( [labeled params] )
           my $manager = Lucy::Index::IndexManager->new(
               host => $hostname,    # default: ""
           );

       ·   host - An identifier which should be unique per-machine.

       ·   lock_factory - A LockFactory.

METHODS

   make_write_lock()
       Create the Lock which controls access to modifying the logical content of the index.

   recycle( [labeled params] )
       Return an array of SegReaders representing segments that should be consolidated.
       Implementations must balance index-time churn against search-time degradation due to
       segment proliferation. The default implementation prefers small segments or segments with
       a high proportion of deletions.

       ·   reader - A PolyReader.

       ·   del_writer - A DeletionsWriter.

       ·   cutoff - A segment number which all returned SegReaders must exceed.

       ·   optimize - A boolean indicating whether to spend extra time optimizing the index for
           search-time performance.

   set_folder(folder)
       Setter for "folder" member.  Typical clients (Indexer, IndexReader) will use this method
       to install their own Folder instance.

   get_folder()
       Getter for "folder" member.

   get_host()
       Getter for "host" member.

   set_write_lock_timeout(timeout)
       Setter for write lock timeout.  Default: 1000 milliseconds.

   get_write_lock_timeout()
       Getter for write lock timeout.

   set_write_lock_interval(timeout)
       Setter for write lock retry interval.  Default: 100 milliseconds.

   get_write_lock_interval()
       Getter for write lock retry interval.

INHERITANCE

       Lucy::Index::IndexManager isa Lucy::Object::Obj.
