- <P>Class hack for Advance AltaVista web search mode originally written by
- John Heidemann <EM><A HREF="http://www.altavista.com">http://www.altavista.com</A></EM>.</P>
- <P>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.</P>
- <P>This class exports no public interface; all interaction should
- be done through WWW::Search objects.</P>

- <H1><A NAME="usage">USAGE</A></H1>
- <P>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:</P>
- <P>(John Heidemann) AND (lsam OR replication) AND NOT (somestupiedword OR thisone)</P>
- <P>(lsam OR replication) AND (John Heidemann) AND NOT (somestupiedword OR thisone)
- </P>
- <PRE>
-
- Batman and Robin and not Joker</PRE>
- <P>Batman and Robin and not (joker or riddler)</P>
- <P>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.</P>
- <P>CASE doesnt matter anymore for the Boolean operators for 'and' will be
- uppercased to 'AND'. This is to make constructing complex queries
- easier.</P>
