Xapian::TermGenerator(3pm) User Contributed Perl Documentation Xapian::TermGenerator(3pm)NAME
Search::Xapian::TermGenerator - Parses a piece of text and generates terms.
DESCRIPTION
This module takes a piece of text and parses it to produce words which are then used to generate suitable terms for indexing. The terms
generated are suitable for use with Search::Xapian::Query objects produced by the Search::Xapian::QueryParser class.
SYNOPSIS
use Search::Xapian;
my $doc = new Search::Xapian::Document();
my $tg = new Search::Xapian::TermGenerator();
$tg->set_stemmer(new Search::Xapian::Stem("english"));
$tg->set_document($doc);
$tg->index_text("The cat sat on the mat");
METHODS
new TermGenerator constructor.
set_stemmer <stemmer>
Set the Search::Xapian::Stem object to be used for generating stemmed terms.
set_stopper <stopper>
Set the Search::Xapian::Stopper object to be used for identifying stopwords.
set_document <document>
Set the Search::Xapian::Document object to index terms into.
get_document <document>
Get the currently set Search::Xapian::Document object.
index_text <text> [<weight> [<prefix>]]
Indexes the text in string <text>. The optional parameter <weight> sets the wdf increment (default 1). The optional parameter
<prefix> sets the term prefix to use (default is no prefix).
index_text_without_positions <text> [<weight> [<prefix>]]
Just like index_text, but no positional information is generated. This means that the database will be significantly smaller, but that
phrase searching and NEAR won't be supported.
increase_termpos [<delta>]
Increase the termpos used by index_text by <delta> (default 100).
This can be used to prevent phrase searches from spanning two unconnected blocks of text (e.g. the title and body text).
get_termpos
Get the current term position.
set_termpos <termpos>
Set the current term position.
get_description
Return a description of this object.
