Search::Xapian::TermGenerator - Parses a piece of text and generates terms.
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.
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");
- 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
-
Returns a string describing this object. (for introspection)
