Search::InvertedIndex::Simple::BerkeleyDB 1.06

Search::InvertedIndex::Simple::BerkeleyDB is a pure Perl module.

See the parent module Search::InvertedIndex::Simple for an explanation of the options dataset and keyset passed in to new().

db_put() writes the index built by Search::InvertedIndex::Simple to an in-RAM database managed by BerkeleyDB.

db_get($key) returns the results of a search as a hash ref.

inflate($result) converts the result hash ref into a single object of type Set::Array.

 ];
 my($keyset) = [qw/address time/];
 my($db) = Search::InvertedIndex::Simple::BerkeleyDB -> new
 (
 dataset => $dataset,
 keyset => $keyset,
 );

 $db -> db_put();

 my($result) = $db -> db_get({address => 'Hea', time => 'T'}); # Returns a hashref.
 my($set) = $db -> inflate($result); # Returns a Set::Array object.

 print $set ? join(',', $set -> print() ) : 'Search did not find any matching records', ". \n";
