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> [<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.
