KinoSearch::Index::PostingList - Term-Document pairings.
my $postings_reader = $seg_reader->obtain("KinoSearch::Index::PostingsReader"); my $posting_list = $postings_reader->posting_list( field => 'content', term => 'foo', ); while ( my $doc_id = $posting_list->next ) { say "Matching doc id: $doc_id"; }
PostingList is an iterator which supplies a list of document ids that match a given term.
See KinoSearch::Docs::IRTheory for definitions of "posting" and "posting list".
Advance the iterator to the first doc id greater than or equal to target. The default implementation simply calls next() over and over, but subclasses have the option of doing something more efficient.
target
target - A positive doc id, which must be greater than the current doc id once the iterator has been initialized.
Returns: A positive doc id, or 0 once the iterator is exhausted.
Proceed to the next doc id.
Return the current doc id. Valid only after a successful call to next() or advance() and must not be called otherwise.
Return the number of documents that the PostingList contains. (This number will include any documents which have been marked as deleted but not yet purged.)
Prepare the PostingList object to iterate over matches for documents that match target.
target - The term to match. If undef, the iterator will be empty.
