Hello all,
I have a question about use the TermGenerator alone by Perl. Someone
asked this question before and his code is in C++.
(http://lists.xapian.org/pipermail/xapian-discuss/2008-November/006109.html).
My code is in Perl. Can I get the term by the position just by
TermGenerator?
my $analyzer = Search::Xapian::TermGenerator->new;
$analyzer->index_text("hello Xapian world");
my $curr_position = $analyzer->get_termpos();
$analyzer->set_termpos(2);
$curr_position = $analyzer->get_termpos();
$analyzer->increase_termpos(1);
$curr_position = $analyzer->get_termpos();
If I set the document and then use $doc to iterate the term list, terms
are order alphabetically. I don't know how to use the positer().
$analyzer->set_document($doc);
my $termlist_begin = $doc->termlist_begin();
$termlist_begin++;
my $term = $termlist_begin->get_document();
Btw, if I want to use ESet, how to assign the text, similar method like
index_text for ESet?
Thank you,
Ying
