WWW::Search::AltaVista - class for searching www.altavista.com
require WWW::Search; $search = new WWW::Search('AltaVista');
This class is an AltaVista specialization of WWW::Search. It handles making and interpreting AltaVista searches http://www.altavista.com.
This class exports no public interface; all interaction should be done through WWW::Search objects.
The default is "any of these words" (OR of query terms).
Add the AND of these words to the query.
Add "this exact phrase" to the query.
Add the OR of these words to the query. This is where the query is placed by default.
Add NOT these words to the query.
Add a boolean expression to the query. Operators are AND, OR, AND NOT, and NEAR. In the browser interface, the boolean expression can not be combined with any other query types listed above. You should probably build the boolean expression with parentheses and spaces and urlescape it.
Pages containing "these words" will be ranked highest.
To restrict the search to U.S. websites, set kgs=1. The default is world-wide, kgs=0.
To restrict the search to pages in English and Spanish, set kls=1. The default is no language restrictions, kls=0.
To restrict the search to HTML pages only, set filetype=html. To restrict the search to PDF pages only, set filetype=pdf. The default is no restriction on page type, filetype=.
To restrict the search to pages from certain domains, set rc=dmn and set swd to a list of desired toplevel domains.
To restrict the search to pages from a particular site, set rc=url and set lh to the site name and path. Leave off the http:// from the site.
To make new back-ends, see WWW::Search, or the specialized AltaVista searches described in options.
