NAME

       Search::Xapian::TermIterator - Iterate over sets of terms.

DESCRIPTION

       This object represents a stream of terms. It overloads "++" for advancing the iterator, or you can explicitly call the "inc" method.  This
       class also overloads "eq", "ne", "==", "!=", and "" (stringification).

METHODS

       new Constructor. Defaults to a uninitialized iterator.

       clone
       inc Advance the iterator by one. (Called implictly by "++" overloading )

       skip_to <tname>
	   Skip the iterator to term tname, or the first term after tname if tname isn't in the list of terms being iterated.

       get_termname
	   Get the name of the current term.

       get_wdf
	   Return the wdf of the current term (if meaningful).

       get_termfreq
	   Return the term frequency of the current term (if meaningful).

       positionlist_begin
	   Return Search::Xapian::PositionIterator pointing to start of positionlist for current term.

       positionlist_end
	   Return Search::Xapian::PositionIterator pointing to end of positionlist for current term.

       get_description
	   Returns a string describing this object.

       equal <termiterator>
	   Checks if a termiterator is the same as this termiterator. Also overloaded as the "eq" and "!=" operators.

       nequal <termiterator>
	   Checks if a termiterator is different from this termiterator. Also overloaded as the "ne" and "!=" operators.

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.
