Tie::Senna - Tie Senna With Hashes


  use Tie::Senna;
  my $senna = Senna::Index->create(...);

  tie %hash, 'Tie::Senna', index => $index;
  # tie %hash, 'Tie::Senna', index => $index, storage => \%storage;
  $hash{$key} = $value;

  foreach my $r ( tied(%hash)->search($query) ) {
    print "matched ", $r->key, " -> score: ", $hash{$r->key}\n";


Tie::Senna ties an existing hash with a senna index.


tie(%hash, 'Tie::Senna', %args)

Tie a Senna with a hash. After tieing, subsequent calls to modify %hash will trigger necessary changes to the underlying senna index, so you can perform searches on it.

%args must contain the 'index' parameter. This must point to a Senna::Index object.

You may optionally specify a reference to hash as the storage parameter. It is recommended that you specify this, as otherwise Tie::Senna will use a plain old in-memory hash, and all data will be lost when the object is garbage collected. You can specify other tied hashes, too:

   use Tie::Senna;
   use DB_File;

   my %storage;
   tie %storage, 'DB_File', ...;

   my $index = Senna::Index->create(...);
   my %senna;
   tie %senna, 'Tie::Senna', index => $index, storage => \%storage;


Perform a full text search on the index and returns a Senna::Cursor object, or a list of Senna::Result objects in list context. You need to access the tied() object from the tied hash to call this method.


Return a reference to the underlying hash that is used as the data storage


Return the underlying Senna::Index object being used.
