KinoSearch::Index::Lexicon - Iterator for a field's terms.
The KinoSearch code base has been assimilated by the Apache Lucy project. The "KinoSearch" namespace has been deprecated, but development continues under our new name at our new home: http://lucy.apache.org/
my $lex_reader = $seg_reader->obtain('KinoSearch::Index::LexiconReader'); my $lexicon = $lex_reader->lexicon( field => 'content' ); while ( $lexicon->next ) { print $lexicon->get_term . "\n"; }
A Lexicon is an iterator which provides access to all the unique terms for a given field in sorted order.
If an index consists of two documents with a 'content' field holding "three blind mice" and "three musketeers" respectively, then iterating through the 'content' field's lexicon would produce this list:
blind mice musketeers three
Seek the Lexicon to the first iterator state which is greater than or equal to target. If target is undef, reset the iterator.
target
Proceed to the next term.
Returns: true until the iterator is exhausted, then false.
Return the current term, or undef if the iterator is not in a valid state.
Reset the iterator. next() must be called to proceed to the first element.
KinoSearch::Index::Lexicon isa KinoSearch::Object::Obj.
