NAME

       Search::Xapian::PositionIterator - Iterate over sets of positions.

DESCRIPTION

       This iterator represents a stream of positions for a term. It overloads "++" for advancing the iterator, or you can explicitly call the
       "inc" method.  This class also overloads "eq", "ne", "==", "!=", "" (stringification) and "0+" (conversion to an integer).

METHODS

       new Constructor. Defaults to an uninitialized iterator.

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

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

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

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

       get_termpos
	   Return the term position the iterator is currently on. Also implemented as conversion to an integer.

       get_description
	   Return a description of this object.  Also implemented as stringification.

NAME

       Search::Xapian::Database - Search database object

DESCRIPTION

       This class represents a Xapian database for searching. See Search::Xapian::WritableDatabase for an object suitable for indexing.  To
       perform searches, this class works with the Search::Xapian::Query object.

METHODS

       new <database>
	   Class constructor. Can either take a path to an existing database or another database class as the first parameter

       clone
	   Return a clone of this class.

       add_database
	   Add an existing database (or group of databases) to those accessed by this object.

       reopen
	   This re-opens the database(s) to the latest available version(s). It can be used either to make sure the latest results are returned,
	   or to recover from a Xapian::DatabaseModifiedError.

       close
	   Close the database. This also implies a commit() unless a transaction is in progress.

       enquire [<query>]
	   Returns a new Search::Xapian::Enquire object. Any extra parameters are passed to set_query.

       get_doccount
	   Returns the number of document indexed in this database.

       get_lastdocid
	   Returns the id of the last used document.

       get_doclength <doc_id>
	   Returns the length of a given document.

       get_document <doc_id>
	   Returns a Search::Xapian::Document object for the given document.

       get_avlength
	   Get the average length of the documents in the database.

       get_termfreq <term>
	   Get the number of documents in the database indexed by a given term.

       term_exists <term>
	   returns true if this term exists in the database, or false otherwise.

       get_description
	   return a description of this object.

       get_spelling_suggestion
	   returns a suggested spelling correction.

       allterms_begin [<prefix>]
	   Returns a Search::Xapian::TermIterator iterating over the termlist for the the entire database.  If the optional prefix argument is
	   non-empty, only terms starting with that string are returned.

       allterms_end [<prefix>]
	   Returns a Search::Xapian::TermIterator pointing to the end of the termlist corresponding to allterms_begin.

       termlist_begin <docid>
	   Returns a Search::Xapian::TermIterator pointing to the start of the termlist for a given document.

       termlist_end <docid>
	   Returns a Search::Xapian::TermIterator pointing to the end of the termlist for a given document.

       positionlist_begin <docid> <term>
	   Returns a Search::Xapian::PositionIterator pointing to the start of the position list for a given term in the given document.

       positionlist_end <docid> <term>
	   Returns a Search::Xapian::PositionIterator pointing to the end of the position list for a given term in the given document.

       postlist_begin <term>
	   Returns a Search::Xapian::PostingIterator pointing to the start of the posting list for a given term.

       postlist_end <term>
	   Returns a Search::Xapian::PostingIterator pointing to the end of the posting list for a given term.

       keep_alive
	   Send a "keep-alive" to remote databases to stop them timing out.

       get_collection_freq <term>
	   Get the number of elements indexed by a certain term.
