NAME

WWW::Search::AltaVista::AdvancedWeb - class for advanced Alta Vista web searching

SYNOPSIS

    require WWW::Search;
    $search = new WWW::Search('AltaVista::AdvancedWeb');

DESCRIPTION

Class hack for Advance AltaVista web search mode originally written by John Heidemann http://www.altavista.com.

This hack now allows for AltaVista AdvanceWeb search results to be sorted and relevant results returned first. Initially, this class had skiped the 'r' option which is used by AltaVista to sort search results for relevancy. Sending advance query using the 'q' option resulted in random returned search results which made it impossible to view best scored results first.

This class exports no public interface; all interaction should be done through WWW::Search objects.

USAGE

Advanced AltaVista searching requires boolean operators: AND, OR, AND NOT, NEAR in all uppercase. Phrases require to be enclosed in braces ( )'s instead of double quotes. Some examples:

(John Heidemann) AND (lsam OR replication) AND NOT (somestupiedword OR thisone)

(lsam OR replication) AND (John Heidemann) AND NOT (somestupiedword OR thisone)

Batman and Robin and not Joker

Batman and Robin and not (joker or riddler)

Comments: For ideal results start your query with the words that matter most in being returned. This module will take those and apply them first for sorting purposes.

CASE doesnt matter anymore for the Boolean operators for 'and' will be uppercased to 'AND'. This is to make constructing complex queries easier.
