NAME

6       Lucy::Index::Lexicon - Iterator for a fieldXs terms.
7

SYNOPSIS

9           my $lex_reader = $seg_reader->obtain('Lucy::Index::LexiconReader');
10           my $lexicon = $lex_reader->lexicon( field => 'content' );
11           while ( $lexicon->next ) {
12              print $lexicon->get_term . "\n";
13           }
14

DESCRIPTION

16       A Lexicon is an iterator which provides access to all the unique terms
17       for a given field in sorted order.
18
19       If an index consists of two documents with a XcontentX field holding
20       Xthree blind miceX and Xthree musketeersX respectively, then iterating
21       through the XcontentX fieldXs lexicon would produce this list:
22
23           blind
24           mice
25           musketeers
26           three

ABSTRACT METHODS

29   seek
30           $lexicon->seek($target);
31           $lexicon->seek();  # default: undef
32
33       Seek the Lexicon to the first iterator state which is greater than or
34       equal to "target".  If "target" is undef, reset the iterator.
35
36   next
37           my $bool = $lexicon->next();
38
39       Proceed to the next term.
40
41       Returns: true until the iterator is exhausted, then false.
42
43   reset
44           $lexicon->reset();
45
46       Reset the iterator.  next() must be called to proceed to the first
47       element.
48
49   get_term
50           my $obj = $lexicon->get_term();
51
52       Return the current term, or undef if the iterator is not in a valid
53       state.
