KinoSearch::Index::Lexicon - Iterator for a field's terms.

    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.

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.
