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> [<wdf_inc> [<prefix>]]
- Indexes the text in string <text>. The optional parameter <wdf_inc> 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> [<wdf_inc> [<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.
